NCP171 LDO Regulator

Pin No. XDFN4 Pin Name Description 1 ECO Low Power and Active mode control pin. Pulling this pin to ground switches the device into Low Power mode and pushing this pin to output voltage switches the device into Active mode. 2 OUT Output pin 3 IN Input pin 4 ENA Enable pin. Driving ENA .

LDO Regulator - Ultra-Low Iq, Dual Power Mode 50 nA, 80 mA 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 th.
