NCP706A Datasheet, PDF (1/9 Pages) ON Semiconductor – Precision Very Low Dropout Voltage Regulator

NCP706A
1 A, 1% Precision Very Low
Dropout Voltage Regulator
with Enable and Active
Discharge
The NCP706A 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 3.0 V fixed output voltage
option. NCP706A 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. Parts feature active output discharge
function.
