NCV8705MTADJTCG

The NCV8705MTADJTCG is a low noise, low power consumption, and low dropout linear voltage regulator from On Semiconductor. With its excellent noise and PSRR specifications, this device is ideal for applications requiring an extremely clean power supply, such as RF receivers, imaging sensors, and audio processors. It features an operating input voltage range of 2.5 V to 5.5 V and an adjustable output voltage range from 0.8 V to 5.5 V. The regulator provides up to 500 mA of output current with a typical dropout voltage of 230 mV at 500 mA. Its ultra-low quiescent current is typically 13 µA, and it exhibits ultra-low noise of 12 µVrms from 100 Hz to 100 kHz. Protection features include over current, over temperature, soft start, and under voltage lockout (UVLO). The device is available in a 6-WDFN (2x2 mm) surface mount package.

This NCV prefix device is suitable for automotive and other applications requiring unique site and control change requirements, being AEC-Q100 qualified and PPAP capable. It is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant. The regulator is stable with a 1 µF ceramic output capacitor and includes active output discharge for fast turn-off. Typical applications include ADAS, infotainment, telematics, general purpose automotive and industrial, and building and factory automation.

Key electrical characteristics include a high PSRR of 71 dB at 1 kHz and ±2% accuracy over load, line, and temperature variations. The internal soft-start limits turn-on inrush current, and thermal shutdown and current limit protections are integrated.
