MITSUMI	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	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
