LDO Regulator - Ultra-Low

Iq, Dual Power Mode

50ꢀnA, 80ꢀmA

NCP171

The NCP171 is a Dual mode LDO offering up to 80 mA in Active

Mode and as low as 50 nA of Iq in Low Power Mode. The Dual Mode

function is selectable with the ECO pin allowing for dynamic

switching between Active and Low Power Modes, ideal in long life

battery powered applications.

The output Voltage in Low Power mode can be lowered by an

internally factory programmed value ranging 50 mV, 100 mV, 150 mV

or 200 mV with respect to the nominal output voltage in Active Mode.

This feature further lowers the application consumption in sleep mode.

The NCP171 is in the SLIQ (Super Low Iq) LDO family and is

available in small XDFN4 1.2 x 1.2 package.
