!TYPICAL APPLICATION CIRCUITS
XC6403A ~ D Series XC6403E Series XC6403F Series
S emi conductor Ltd.
The XC6403 series are highly precise, low noise, positive voltage low
dropout regulators with built-in voltage detector. They are fabricated
using Torex’s CMOS process. Performance features of the series
includes high ripple rejection and low dropout voltage, and the series
features a voltage reference, an error amplifier, a current limiter and a
phase compensation circuit plus a driver transistor.
Detect voltage is selectable in 100mV increments within the range of
0.9V to 5.5V and the LDO output voltage is selectable within a range of
0.9V to 5.6V, also in 100mV increments.
The series is also compatible with low ESR ceramic capacitors which
give added output stability. This stability can be maintained even during
load fluctuations due to the excellent transient response of the series.
The current limiter's foldback circuit also operates as a short circuit
protection for the output current limiter and the output pin.
The series provides options to the user to select from a variety of circuit
features, such as detector monitoring, detector output logic, CE and EN
pin input logic, and internal pull-up / down resistance.
The IC's internal regulator circuit can be placed in stand-by mode via the
EN function (XC6403 A to C series). The whole IC can be put in to
stand-by mode via the CE function with the XC6403D series (semi-
custom). In the stand-by mode, power consumption is greatly reduced.
The XC6403 A and B series features the toggle operation function. The
regulator output can be OFF when the XC6403B series detects voltage
(semi-custom).
The XC6403E series can monitor another power source by using the
VSEN pin (semi-custom).
The XC6403F series can delay the detector output: the delay time can be
controlled by the use of an external capacitor (semi-custom).

VROUT
The XC6403 series regulator offers a combination of current limit and circuit protection by means of a built-in fixed current limiter circuit and a foldback
circuit. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in
output voltage, the foldback circuit operates, the output voltage drops further and output current decreases. When the output pin is shorted, a current of
about 50mA flows.
CL
0.9 ~1.2V 1.3 ~ 1.7V
The voltage, divided by resistors R1 & R2 which are connected to the VROUT pin is compared with the internal reference voltage by the error amplifier.
The P-Channel MOSFET, which is connected to the VROUT pin, is then driven by the subsequent output signal. The output voltage at the VROUT pin is
controlled & stabilized by negative feedback.
The current limit circuit and short circuit protection operate in relation to the level of output current. Further, the voltage regulator's internal circuitry can be
shutdown via the EN or CE pin's signal.
With the XC6403 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase compensation circuit is built-in
to the regulator. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) be connected as close as
possible, between the output pin (VROUT) and the VSS pin. Please use an output capacitor (CL) with a capacitance, based on the chart below. We also
suggest an input capacitor (CIN) of 1µF : this should be connected between VIN and VSS in order to stabilize input power source.
For the XC6403A, B, C type, in stand-by, if a voltage of the recovery voltage is present at the VROUT pin (from another power source), the VDOUT pin
will be high impedance mode, and the pull up voltage will be output at VDOUT. By connecting the Cdelay pin to a capacitor (Cd), the XC6403F series
can apply a delay time to VDOUT voltage when releasing voltage. The delay time can be calculated from the internal resistance, Rdelay (2MΩ fixed) and
the value of Cd as per the following equation.
Delay Time = Cdelay x Rdelay x 0.7
The series' detector function monitors the voltage divided by resistors R3 & R4 which are connected to the VROUT pin or the VIN pin or the VSEN pin, as
well as monitoring the voltage of the internal reference voltage source via the comparator. The VDSEN pin has options (please refer to the Selection
Guide, item 4 on page 2). A 'High' or 'Low' signal level can be output from the VDOUT pin when the VD pin voltage level goes below the detect voltage.
The VD output logic has options (please refer to the Selection Guide, item 5 on page 2). As VDOUT is an open-drain N-channel output, a pull-up resistor
of about 220KΩ is needed to achieve a voltage output. Because of hysteresis at the detector function, output at the VDOUT pin will invert when the
detect voltage level increases above the release voltage (105% of the detect voltage). Even when the XC6403A, B, C, series are in stand-by mode, the
voltage detector function operates and the output voltage at VDOUT will output according to the voltage level at VDSENSE voltage.

<Toggle Operation>
XC6403 * E ~ K Active HIGH with no pull down
XC6403 * L ~ P
Input Current = VIN voltage / Pull Up Resistance
In stand-by mode, the above input current can be reduced by connecting a pull-up resistor between VROUT and VDOUT.
Note that as the XC6403*E to K types of the XC6403A to D series are 'Active HIGH / No Pull Down' and XC6403*R to U types of the XC6403A to D
series are 'Active LOW / No Pull Up', operations will become unstable with the CE pin open (See the chart below).
SERIES CE INPUT LOGIC
EN Logic Active "HIGH"
The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6403A, B, C series. In shutdown mode, output at the
VROUT pin will be pulled down to the VSS level via R1 & R2. The whole IC's circuitry can be shut down via CE pin with the XC6403D series and power
consumption can be reduced to around 0 µA. While the voltage detector is in shutdown mode, the voltage detector output is in a post-detection state.
When choosing Detect L, input current can be set by using the following formula.
The XC6403 A and B series have a built-in toggle ON/OFF switch which repeats an on/off operation via the EN pin's leading edge signal when the EN
logic is Active HIGH, and via the EN pin's falling edge signal when the EN logic is Active LOW (Please also refer the figure below). The EN input signal
duration should be over 500nsec. If the EN input signal is less than 500nsec, it is possible that the circuit fails to respond and the toggle function does
not operate. To operate the toggle function properly when the EN pin voltage noise is large, a RC filter should be used to reduce the noise in the signal
to the EN pin. In the case where input delay time is required, it is possible to set the time constant by connecting an RC network to the EN pin.
We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the EN or CE pin. If this IC is used with the correct specifications for
the EN or CE pin, the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry if a
voltage other than VIN or VSS is applied.

Block Diagram for XC6403B series Timing Chart
The type which applies the reset signal to the T-FF internally via a one-shot pulse circuit changes the voltage detector comparator output signal to a one-
shot signal internally. Like the type which applies the reset directly via the signal from voltage detector function, this type also applies the reset to the T-
FF and sets the VR output to OFF when the input voltage (VIN Sense type) and output voltage (VROUT Sense type) drop below the detect voltage level.
This type can return the VR output by inputting a toggle signal, even when the Sense pin voltage (VIN or VROUT pin voltage) is below the release
voltage.
Please refer to the block diagram below and the timing chart on the following page. Please choose the option suitable to the application.
For the XC6403B series, there are two types of toggle selection; one is a T-type flip-flop (T-FF) used for toggle operation which can be reset internally by
a signal directly from the voltage detector (VIN Sense type only. See also the Selection Guide on page 2). The other type is where the reset is applied
internally through a one shot pulse circuit (VIN, VROUT type only. See also the Selection Guide on page 2).
The type, which applies the reset directly via the signal from the voltage detector function, applies the voltage detector comparator's output signal (reset
signal) to the reset of T-FF reset, and turns the VR output OFF when the input voltage decreases below the detect voltage due to battery consumption,
etc.. In order to return the VR output, apply a voltage larger than the release voltage to VIN and input a toggle signal to the T-FF. In the case where
input voltage is below the release voltage, the VR output does not return even though the toggle signal is input into the T-FF.
