1A Low Dropout Regulator with Enable  
Features  
General Description  
„
Adjustable Output from 1.2V to 4.8V Using Ex-  
The G961 is a high performance positive voltage  
regulator designed for use in applications requiring  
very low dropout voltage at up to 1 Amps. Since it has  
superior dropout characteristics compared to regular  
LDOs, it can be used to supply 2.5V on motherboards  
or 1.5V, 1.8V on peripheral cards from the 3.3V supply  
thus allowing the elimination of costly heatsinks. An  
enable pin further reduces power dissipation while  
shut down. The G961 provides excellent regulation  
over variations in line, load and temperature.
