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.
