NCP706
1A, 1% Precision Very Low
Dropout Voltage Regulator
with Enable
The NCP706 is a Very Low Dropout Regulator which provides up to
1 A of load current and maintains excellent output voltage accuracy of
1% 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 2.1 V and 2.2 V fixed output
voltage options. NCP706 is fully protected against overheating and
output short circuit.
Very small 8−pin XDFN8 1.6 x 1.2, 04P package makes the device
especially suitable for space constrained portable applications such as
tablets and smartphones.
