Io=1A,Vin=27V, eSOIC8 Linear Regulator IC
NR301E
Sep/19/2013
General Descriptions
NR301E is the low saturation voltage type Io=1.0A linear
regulator IC built in the exposed SOIC8 package.
The output voltage Vo is adjustable by the external resistor.
In this IC, start-up and shut-down are possible by the
external signal input.
Over-current protection and thermal protection are built in
as a protection function.
A low-ESR capacitor like a ceramics capacitor can be used
for the output capacitor.
