NCV59749MNADJTBG

The NCV59749MNADJTBG from On Semiconductor is a dual-rail, very low dropout voltage regulator designed for high-current applications. It can deliver over 3.0 A with a typical dropout voltage of 120 mV at full load. The device supports an adjustable output voltage down to 0.8 V and operates within an input voltage range of 0.8 V to 5.5 V.

Key features include programmable soft-start and an open-drain power-good output, providing enhanced control and monitoring capabilities. Internal protection mechanisms such as current limit and thermal shutdown are integrated for reliability. The regulator is stable with ceramic and other output capacitors greater than or equal to 2.2 µF.

This regulator is available in a 20-QFN (5x5) package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The NCV prefix indicates suitability for automotive and other applications requiring unique site and control change requirements, with AEC-Q100 qualification and PPAP capability.

Applications include point-of-load regulation in automotive, consumer, and industrial equipment, as well as power supplies for FPGAs, DSPs, and logic circuits. It can also be used for post-regulation in switching power supplies.
