NCP59748
1.5 A, Dual-Rail Very
Low‐Dropout Linear
Regulator with
Programmable Soft‐Start
The NCP59748 is dual−rail very low dropout voltage regulator,
capable of providing an output current in excess of 1.5 A with a
dropout voltage of 60 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 on
both QFN and DFN versions.
The NCP59748 is offered in DFN10 3×3 and QFN20 5×5 packages.
