AN78xx/AN78xxF Series
3-pin positive output voltage regulator (1 A type)
■ 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.
■ 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

Note 1) The specified condition Tj = 25°C means that the test should be carried out within so short a test time (within 10ms) that the
characteristic value drift due to the chip junction temperature rise can be ignored.
Note 2) Unless otherwise specified, VI = 10V, IO = 500mA, CI = 0.33µF and CO = 0.1µF.
