Overview

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.
