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.

Note 1) The specified condition T
j
= 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, V
I
= 19V, I
O
= 500mA, C
I
= 0.33µF and C
O
= 0.1µF.
