NCP59749
3.0 A, Dual-Rail Very
Low‐Dropout Linear
Regulator with
Programmable Soft‐Start
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.
