High-Precision Three-Pin Regulator MM1257
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.
