AN7800R

Positive Output Voltage Regulators with Reset pin (1A/500mA Type)

Panasonic Corporation 

AN7800R/AN78M00R Series

Positive Output Voltage Regulators with

Reset pin (1A/500mA Type)

s Overview

The AN7800R and the AN78M00R series are the fixed

positive output voltage regulators with reset pin. Stabi-

lized fixed output voltage is obtained from unstable DC

input voltage without using any external components.

Three types of output voltage, 5V, 9V and 12V, are avail-

able for the AN7800R series, and four types, 5V, 8V, 9V

and 12V, are available for the AN78M00R series. They

can be used in power circuits with current capacitance

1A/500mA. ON/OFF of output voltage can be controlled

by the reset pin.

s Features

500mA (AN78M00R)

• Output voltage :5V, 9V, 12V (AN7800R)

:8V (AN78M08R)

• Short-circuit current limiting built-in

• Thermal overload protection built-in

• Output transistor safe area compensation

• ON/OFF of output voltage can be controlled by reset

pin.
