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.
