Microminiature Low-Noise, Low-Saturation Three-Pin Regulator MM1320

Microminiature Low-Noise, Low-Saturation Three-Pin Regulator

Monolithic IC MM1320

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

2. Output noise voltage

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
