AN7800R/AN78M00R Series
Positive Output Voltage Regulators with
Reset pin (1A/500mA Type)
■ Overview
The AN7800R and the AN78M00R series are the fix ed
positive output voltage regulators with reset pin. Stabilized 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 available 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.

Note 1) The specified condition Tj=25˚C means that the test should be carried out with the test time so short (within 10ms) that the
drift in characteristic value due to the rise in chip junction temperature can be ignored.
