Definition of technical terms
Relating Characteristic
♦
♦♦
♦
Output Voltage (Vout)
The output voltage is specified with Vin=(Vout
TYP
+1V)
and Iout=5mA.
♦
♦♦
♦
Maximum Output Current (Iout MAX)
The rated output current is specified under the condition
where the output voltage drops 0.3V the value specified
with Iout=5mA. The input voltage is set to Vout
TYP
+1V
and the current is pulsed to minimize temperature effect.
♦
♦♦
♦
Dropout Voltage (Vdrop)
The dropout voltage is the difference between the input
voltage and the output voltage at which point the regulator
starts to fall out of regulation. Below this value, the output
voltage will fall as the input voltage is reduced. It is
dependent upon the load current and the junction
temperature.
♦
♦♦
♦
Line Regulation (LinReg)
Line regulation is the ability of the regulator to maintain a
constant output voltage as the input voltage changes. The
line regulation is specified as the input voltage is changed
from Vin=Vout
TYP
+1V to Vin=Vout
TYP
+6V. It is a pulse
measurement to minimize temperature effect.
♦
♦♦
♦
Load Regulation (LoaReg)
Load regulation is the ability of the regulator to maintain a
constant output voltage as the load current changes. It is a
pulsed measurement to minimize temperature effects with
the input voltage set to Vin=Vout
TYP
+1V. The load
regulation is specified output current step conditions of
5mA to 100mA.
♦
♦♦
♦
Ripple Rejection (R.R)
Ripple rejection is the ability of the regulator to attenuate the
ripple content of the input voltage at the output. It is specified
with 200mV
rms
, 1kHz super-imposed on the input voltage,
where Vin=Vout+1.5V. Ripple rejection is the ratio of the
ripple content of the output vs. input and is expressed in dB.
♦
♦♦
♦Standby Current (Istandby)
Standby current is the current, which flows into the
regulator when the output is turned off by the control
function (Vcont=0V).
Relating Protection Circuit
♦
♦♦
♦
Over Current Sensor
The over current sensor protects the device when there is
excessive output current. It also protects the device if the
output is accidentally connected to ground.
♦
♦♦
♦
Thermal Sensor
The thermal sensor protects the device in case the junction
temperature exceeds the safe value (T
J
=150
°
C). This
temperature rise can be caused by external heat, excessive
power dissipation caused by large input to output voltage
drops, or excessive output current. The regulator will shut
off when the temperature exceeds the safe value. As the
junction temperatures decrease, the regulator will begin to
operate again. Under sustained fault conditions, the
regulator output will oscillate as the device turns off then
resets. Damage may occur to the device under extreme
fault.
Please reduce the loss of the regulator when this protection
operate, by reducing the input voltage or make better heat
efficiency.
* In the case that the power, Vin × Ishort(Short Circuit Current),
becomes more than twice of the maximum rating of its power
dissipation in a moment, there is a possibility that the IC is
destroyed before internal thermal protection works.
♦
♦♦
♦
Reverse Voltage Protection
Reverse voltage protection prevents damage due to the
output voltage being higher than the input voltage. This
fault condition can occur when the output capacitor
remains charged and the input is reduced to zero, or when
an external voltage higher than the input voltage is applied
to the output side

Board Layout
PCB Material: Glass epoxy (t=1.0mm)
Please do derating with 4.0mW/°C at Pd=400mW and 25°C
or more. Thermal resistance (θja) is=250°C/W.
The package loss is limited at the temperature that the internal
temperature sensor works (about 150°C). Therefore, the
package loss is assumed to be an internal limitation. There is
no heat radiation characteristic of the package unit assumed
because of the small size. The device being mounted on the
PCB carries heat away. This value changes by the material and
the copper pattern etc. of the PCB. The losses are
approximately 400mW. Enduring these losses becomes
possible in a lot of applications operating at 25°C.
The overheating protection circuit operates when there are a
lot of losses with the regulator (When outside temperature is
high or heat radiation is bad). The output current cannot be
pulled enough and the output voltage will drop when the
protection circuit operates. When the junction temperature
reaches 150°C, the IC is shut down. However, operation
begins at once when the IC stops operation and the
temperature of the chip decreases.
How to determine the thermal resistance when mounted
on PCB
The thermal resistance when mounted is expressed as follows:
Tj=θja×Pd+Ta
Tj of IC is set around 150°C. Pd is the value when the thermal
sensor is activated.
If the ambient temperature is 25°C, then:
150=θja×Pd+25
θja=125/Pd (°C /mW)
Noise bypass capacitor
The noise and the ripple rejection characteristics depend on
the capacitance on the Np terminal.
The ripple rejection characteristic of the low frequency region
improves by increasing the capacitance of Cnp.
A standard value is Cnp=0.001µF. Increase Cnp in a design
with important output noise and ripple rejection requirements.
The IC will not be damaged if the capacitor value is increased.
The on/off switching speed changes depending on the Np
terminal capacitance. The switching speed slows when the
capacitance is large.

ESR stability
Linear regulators require input and output capacitors in order
to maintain the regulator's loop stability. If 0.47µF or larger
capacitor is connected to the output side, the IC provides
stable operation at any voltage (0.9V≤Vout
TYP
≤1.2V). (The
capacitor must be larger then 0.47µF at all temperature and
voltage range) If the capacitor with high Equivalent Series
Resistance (ESR) (several ohms) is used, such as tantalum
capacitor etc., the regulator may oscillate. Please select parts
with low ESR.
Due to the parts are uneven, please enlarge the capacitance as
much as possible. With larger capacity, the output noise
decreases more. In addition, the response to the load change,
etc. can be improved. The IC won’t be damaged by enlarging
the capacity.
A recommended value of the application is as follows.

Generally, a ceramic capacitor has both temperature
characteristic and voltage characteristic. Please consider both
characteristics when selecting the part. The B curves are the
recommend characteristics.
