PG2  
NC  
dual-output low-dropout voltage regulators with  
integrated SVS (RESET, POR, or power on reset)  
and power good (PG) functions. These devices  
are capable of supplying 1 A and 2 A by regulator  
1 and regulator 2 respectively. Quiescent current  
is typically 185 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.
