AN78xx/AN78xxF Series
3-pin positive output voltage
regulator (1 A type)
I Overview
The AN78xx series and the AN78xxF series are 3pin, fixed positive output type monolithic voltage
regulators. Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components. 11 types of fixed output voltage are available; 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V, and 24V. They can be used widely in power circuits with current capacity of up to 1A. AN78xx series
