3.0 A, Dual-Rail Very

Low‐Dropout Linear

Regulator with

Programmable Soft‐Start

http://onsemi.com

The NCP59749 is dual−rail very low dropout voltage regulator that

is capable of providing an output current in excess of 3.0 A with a

dropout voltage of 120 mV typ. at full load current. The devices are

stable with ceramic and any other type of output capacitor ≥ 2.2 mF.

This series contains adjustable output voltage version with output

voltage down to 0.8 V. Internal protection features consist of built−in

thermal shutdown and output current limiting protection.

User−programmable Soft−Start and Power Good pins are available.

The NCP59749 is available in QFN20 5x5 package.
