NCP57302, NCV57302
3.0 A, Very Low-Dropout
(VLDO) Fast Transient
Response Regulator
The NCP57302 is a high precision, very low dropout (VLDO), low
minimum input voltage and low ground current positive voltage
regulator that is capable of providing an output current in excess of
3.0 A with a typical dropout voltage of 315 mV at 3.0 A load current
and input voltage from 1.8 V and up. The device is stable with ceramic
output capacitors. The device can withstand up to 18 V max input
voltage.
Internal protection features consist of output current limiting,
built−in thermal shutdown and reverse output current protection.
Logic level enable pin is available. The NCP57302 is an adjustable
voltage device and is available in D2PAK−5 package.
