Overview
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.
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.
