NCP3520/NCP3521  
LDO Regulator Controller  
The NCP3520 / NCP3521 parts are Low Drop Out (LDO) regulator  
controllers for applications requiring highcurrents 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.
