with integrated SVS (RESET, POR, or power on  
reset) and power good (PG) functions. These  
devices are capable of supplying 250 mA and 125  
mA by regulator 1 and regulator 2 respectively.  
Quiescent current is typically 190 µA at full load.  
Differentiated features, such as accuracy, fast  
transient response, SVS supervisory circuit  
(power on reset), manual reset input, and  
independent enable functions provide a complete  
system solution.
