AN78Lxx/AN78LxxM Series
3-pin positive output voltage regulator (100 mA type)
I Overview
pin fixed positive output type monolithic voltage regula-
tor.
unstable DC input voltage without using any external
parts. 12 types of fixed output voltage are available; 4V,
5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V and 24V.
They can be used widely as power circuits with a current
capacity of up to 100mA.
