n Overview
The AN78L00 series is 3-pin fixed positive output type
monolithic voltage regulators.
A Stabilized fixed output voltage is obtained from an
unstable DC input voltage without using any external
parts. Eleven types of fixed output voltage are available
from 4V through 10V, 12V, 15V, 18V, 20V, and 24V. They
can be used widely as power circuits with a current
capacitance of up to 100mA.
n Features
• No external components
• Output voltage:4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V,
15V, 18V, 20V, 24V
• Internal short-circuit current limiting
• Internal thermal overload protection
