AN7800

AN7800/AN7800F Series 3-pin Positive Output Voltage Regulator (1A Type) 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 voltage 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.
