AN78N00 Datasheet, PDF (1/9 Pages) Panasonic Semiconductor – 3-pin Positive Output Voltage Regulator 300mA Type

AN78N00 Series
3-pin Positive Output Voltage Regulator (300mA Type)
s Overview
The AN78N00 series is 3-pin fixed positive output volt-
age regulators. Stabilized fixed output voltage is obtained

nal components. 12 types of fixed output voltage are avail-
able ; 4V, 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 300mA.
