Overview
Voltage Regulators AN78Lxx/AN78LxxM Series 3-pin positive output voltage regulator (100 mA type) I Overview The AN78Lxx series and the AN78LxxM series are 3pin fixed positive output type monolithic voltage regulator.
A stabilized fixed output voltage is obtained from an 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.
