High-Precision Three-Pin Regulator MM1257

MITSUMI

High-Precision Three-Pin Regulator

Monolithic IC MM1257

Outline

This IC is a high-precision high-voltage stabilized power supply device which stands out from ordinary low-

saturation three-pin regulators.

It can be used at a wide range of output voltages, from 3V to 12V, delivering output currents up to 100mA. It

is one of a series of devices available at lower prices than previous regulators.

Features

1. Input current

27V max.

2. Output noise voltage

3. Maximum output current

4. No-load input current

5. Thermal shutdown circuit provided

6. Output voltage ranks

200µV^RMStyp.

100mA max.

500µA typ.
