onsemi Voltage Regulators - Linear, Low Drop Out (LDO) Regulators NCP717CMX220TCG

The NCP717CMX220TCG is a low dropout (LDO) linear voltage regulator designed to provide a stable output of 2.2 V with a maximum output current of 300 mA. It operates within an input voltage range of 1.8 V to 5.5 V and features a very low quiescent current of approximately 25 µA, making it suitable for battery-powered applications. The device offers low noise performance, with an output noise voltage of 22 µVRMS across a frequency range of 100 Hz to 100 kHz, and a typical dropout voltage of 175 mV at 300 mA load. The NCP717CMX220TCG ensures high accuracy with a tolerance of ±2% over load, line, and temperature variations. It includes thermal shutdown and current limit protections for enhanced reliability. The regulator is stable with a minimum output capacitance of 1 µF, and it is packaged in a compact XDFN 1.0 x 1.0 mm format, which is advantageous for space-constrained designs. Typical applications include mobile devices, wireless handsets, and portable medical equipment.
