NCP171AMX080060TCG

The NCP171AMX080060TCG from ON Semiconductor is a dual-mode LDO (Low Dropout) regulator designed for ultra-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 regulator 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 in 50 mV steps. The dual-mode functionality is selectable via an ECO pin, allowing dynamic switching between 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 relative to the Active Mode output voltage, 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 a high PSRR of 65 dB at 1 kHz. Protection features include current limitation and thermal shutdown. The NCP171AMX080060TCG is available in a compact 4-XDFN (1.2x1.2) package with an exposed pad for improved thermal performance. It is suitable for surface mount applications.

Typical applications for this LDO regulator include IoT devices, RFID tags, portable communication equipment, and consumer electronics where power efficiency and small form factor are critical.
