This IC is a regulator IC that provides ultra-low current consumption (0.8µA), and low input voltage
(V
O
+0.3~6.0V), and has been developed using the CMOS process. Moreover, in addition to characteristics
such as ultra-low current consumption and low dropout voltage, it supports long lifetime of batteries with a
chip enable function.
The mount area is set to 1.10x1.40mm using a surface mount type leadless 4pin package, whichrealizes
microminiaturization.

Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. The ESR of capacitor must be defined in ESR stability area.
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be used more than 0.1µF and B temperature characteristics.
3. The wire of V
CC
and GND is required to print full ground plane for noise and stability.
4. The input capacitor must be connected a distance of less then 1cm from input pin.
5. In case the output voltage is above the input voltage, the overcurrent flow by internal parastic diode from
output to input.
