NCP3520/NCP3521

LDO Regulator Controller

The NCP3520 / NCP3521 parts are Low Drop Out (LDO) regulator

controllers for applications requiring high−currents and ultra low

dropout voltages. The use of an external NMOS driver allows the user

to adapt the device to a multitude of applications depending on system

requirements for current and dropout voltage.
