NCP708/D
NCP708
1 A, 1% Precision Very Low
Dropout Voltage Regulator
with Enable
The NCP708 is a Very Low Dropout Regulator which provides up to
1 A of load current and maintains excellent output voltage accuracy of
1.5% including line, load and temperature variations. The operating
input voltage range from 2.4 V up to 5.5 V makes this device suitable
for Li−ion battery powered products as well as post−regulation
applications. The product is available in 3.3 V fixed output voltage
option. Other voltage options are possible on request. NCP708 is fully
protected against overheating and output short circuit.
Small 6−pin UDFN6 3x3 package makes the device especially
suitable for space constrained applications.
