NCP171AMX165160TCG

The ON Semiconductor NCP171AMX165160TCG is a dual-mode LDO regulator from the SLIQ family, designed for low quiescent current applications. It provides up to 80 mA in Active Mode and can reduce consumption to as low as 50 nA in Low Power Mode, making it ideal for long-life battery-powered devices.

The device features an operating input voltage range of 1.7 V to 5.5 V and an output voltage range of 0.6 V to 3.3 V, adjustable in 50 mV steps. The dual-mode functionality is selectable via the ECO pin, allowing dynamic switching between Active and Low Power Modes. The output voltage in Low Power mode can be internally factory programmed with an offset of 50 mV, 100 mV, 150 mV, or 200 mV with respect to the nominal output voltage in Active Mode, further reducing power consumption during sleep states.

Key electrical specifications include a low dropout voltage of 41 mV typical at 80 mA, ±2% output voltage accuracy in Active Mode, and high PSRR of 65 dB at 1 kHz. Protection features include current limitation and thermal shutdown. The NCP171AMX165160TCG is available in a compact 4-XDFN (1.2x1.2) package with surface mount mounting type.

Typical applications for this LDO regulator include IoT devices, RFID tags, portable communication equipment, and consumer electronics where low power consumption and small package size are critical design considerations.
