AN79N00 Datasheet, PDF (1/9 Pages) Panasonic Semiconductor – 3-pin Negative Output Voltage Regulator 300mA Type

AN79N00 Series
3-pin Negative Output Voltage Regulator (300mA Type)
s Overview
The AN79N00 series is 3-pin fixed negative output volt-
age regulators. Stabilized fixed output voltage is obtained
from unstable DC input voltage without using any exter-
nal components. 12 types of output voltage are available
; –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.
