NCP706B fiche technique
NCP706B, NCP706AB
1 A, 1% Precision Very Low
Dropout Voltage Regulator
with Enable
The NCP706B/AB are a Very Low Dropout Regulators family
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. NCP706B/AB are fully protected against
overheating and output short circuit and includes latched OCP
protection which automatically latches−off the device in the case of a
short circuit event and the NCP706AB has internal active discharge
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.
