n 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.
