AN7805F Datasheet, PDF (1/10 Pages) Panasonic Semiconductor – 3-pin positive output voltage regulator (1 A type)

Voltage Regulators
AN78xx/AN78xxF Series
3-pin positive output voltage regulator (1 A type)
I Overview
The AN78xx series and the AN78xxF series are 3-
pin, fixed positive output type monolithic voltage regu-
lators. Stabilized fixed output voltage is obtained from
unstable DC input voltage without using any external
components. 11 types of fixed output voltage are avail-
able; 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V, and
24V. They can be used widely in power circuits with cur-
rent capacity of up to 1A.
I Features
• No external components
• Output voltage: 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V,
20V, 24V
• Built-in overcurrent limit circuit
• Built-in thermal overload protection circuit
• Built-in ASO (area of safe operation) protection circuit
