5 V Low Drop Voltage Regulator
Functional description
4 Functional description
Application
The IC regulates an input voltage VI in the range of 5.5 V < VI< 40 V to a nominal output voltage of VQ=5.0V.
A reset signal is generated for an output voltage of VQ<VRT (typ. 4.5 V). The reset delay can be set with an
external capacitor. The device has two logic inputs. A voltage of VE2 > 4.0 V applied to the E2-pin (e.g. by
ignition) turns the device on. Depending on the voltage on pin E6 the IC may be kept in Hold active-state even
if VE2 goes to low level (see Table 6). This makes it simple to implement a self-holding circuit without external
components. When the device is turned off, the output voltage drops to 0 V and current consumption tends
towards 0 μA.
Design notes for external components
The input capacitor CI is necessary for compensation of line influences. The resonant circuit consisting of lead
inductance and input capacitance can be damped by a resistor of approximately 1 in series with CI. The
output capacitor is necessary for the stability of the regulating circuit. Stability is specified at values of
CQ22 μF and an ESR of 3 within the operating temperature range.
Circuit description
The control amplifier compares a reference voltage, which is kept highly accurate by resistance adjustment,
to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer.
Saturation control as a function of the load current prevents any over-saturating of the power element.
The reset output RO is in high-state if the voltage on the delay capacitor CD is greater or equal VUD. The delay
capacitance CD is charged with the current ID for output voltages greater than the reset threshold VRT. If the
output voltage drops below VRT a fast discharge of the delay capacitor CD sets in and as soon as VCD drops below
VLD the reset output RO is set to low-level (see Figure 6). The reset delay can be set within a wide range by
dimensioning the capacitance of the external capacitor.
