Outline

This IC is a microminiature low-noise stabilized power supply device featuring a highly precise output voltage and a small input/output voltage difference of only 0.15V at an output current of 60mA.

The IC delivers output currents of up to 200mA, and through use of a noise pin output noise is diminished even further. An on/off pin can be used to turn the output on and off.

Features

1. Input/output voltage difference 0.15V typ. (IO=60mA)

2. Output noise voltage 30µVRMS typ. (Cn=0.01µF)

3. Maximum output current 150mA max.

4. No-load input current 170µA typ.

5. With internal overcurrent protection and thermal shutdown circuits

6. Output voltage ranks 2~3.3V (0.1 V steps) 3.5V, 4V, 4.5V, 5V

7. Output on/off control function High : ON, Low : OFF

Applications

1. Cordless phones

2. Portable phones, PHS

3. Portable minidiscs

4. Other portable equipment which uses batteries
