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.
