Linear Regulator  
http://onsemi.com  
The NCP1578 is a voltage mode synchronous step-down controller  
for high performance systems intended to be used in battery-powered  
systems. The NCP1578 includes a high efficiency PWM controller  
with adjustable output, and a 5 V/50 mA linear regulator. A pin is  
provided to enable or disable forced PWM mode of operation. An  
internal power good voltage monitor tracks the SMPS output.  
NCP1578 also features soft-start sequence, UVLO for linear regulator  
and switcher, overvoltage protection, overcurrent protection, and  
thermal shutdown. The IC is packaged in QFN20.
