n Overview
The AN78M00 and the AN78M00F series are 3-pin
fixed positive output voltage regulators. Stabilized fixed
output voltage is obtained from unstable DC input volt-
age 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 capacitance up to 500mA.
n Features
• No external components
• Output voltage:5V, 6V, 7V, 8V, 9V, 10V, 12V,
15V, 18V, 20V, 24V
• Short-circuit current limiting built-in
• Thermal overload protection built-in
• Output transistor safe area compensation
