Use of the CMOS process allows low current consumption, and it has superior ripple rejection ratio and
transient response compared to conventional CMOS process regulator ICs, making it ideal for use in portable
communications devices.
Ceramic capacitors can be used for the output capacitors.
Ideal for small, portable devices as SOT-25 and WLCSP are used for the package.

3. High precision output voltage ±2%
4. Output current 150mA
5. Input/output voltage difference 0.23V typ. (Io=100mA, 3V output)
6. High ripple rejection ratio 80dB typ.
7. Built-in short-circuit restriction circuit 30mA typ.
8. Wide operating temperature range
-
30~+85°C
9. Output voltage 1.8~5.0V (0.1V step)
Applications
1. Constant voltage power supply for devices that use batteries
2. Constant voltage power supply for portable communications devices
3. Constant voltage power supply for household electronics products

· Input Capacitor Ceramic Capacitor 2.2µF
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 2.2µF or 4.7µF and B temperature characteristics.
3. The wire of VCC and GND is required to print full ground plane for noise and stability.
The input capacitor must be connected a distance of less than 1cm from input pin.
