onsemi NCP171 dual-mode LDO with up to 80 mA in active mode
The NCP171 from onsemi is a dual-mode LDO, offering up to 80 mA in Active Mode and as low as 50 nA of quiescent current (IQ) in Low Power Mode
The NCP171 from onsemi is a dual-mode LDO, offering up to 80 mA in Active Mode and as low as 50 nA of quiescent current (IQ) in Low Power Mode. The Dual Mode function is selectable with the ECO pin, allowing for dynamic switching between the Active and Low Power Mode, which is perfectly suited for long-life battery-powered wireless applications. The output voltage in the Low Power Mode can be lowered by an internally factory programmed value of 50 mV, 100 mV, 150 mV or 200 mV, with respect to the nominal output voltage in Active Mode.
