s Overview
The AN7800 series and the AN7800F series are 3-pin
fixed positive output voltage regulators. Stabilized fixed
output voltage is obtained from unstable DC input volt-
age without using 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 up to 1A.
s Features
No external components
Output voltage:5V, 6V, 7V, 8V, 9V, 10V,
12V, 15V, 18V, 20V, 24V
Internal short-circuit current limiting
Internal thermal overload protection
Output transistor safe area compensation
