Regulator ICs

Low saturation voltage type regulator
with ON / OFF switch

BAST series

The BAST series are variable, fixed output low drop-out type voltage regulators with an ON / OFF switch. These
regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage.
Fixed output voltages are 3V∗, 3.3V, 5V, 6V∗ 7V , 8V, 9V, 10V, 12V, and 15V∗. The maximum current capacity is 1A for
each of the above voltages. (Items marked with an asterisk are under development.)

Applications

Constant voltage power supply

Features

1) Built-in overvoltage protection circuit, overcurrent
protection circuit and thermal shutdown circuit.

2) TO220FP-5 package can be used in wide range of
applications.

3) 0µA (design value) circuit current when switch is off.

4) Richly diverse lineup.

5) Low minimum I / O voltage differential.
