FEATURES  
DESCRIPTION  
The TPS7A65xx-Q1 is a family of low-dropout linear  
voltage regulators designed for low power  
consumption and quiescent current less than 25 µA in  
light-load applications. These devices feature  
integrated overcurrent protection and a design to  
achieve stable operation even with low-ESR ceramic  
output capacitors. A low-voltage tracking feature  
allows for a smaller input capacitor and can possibly  
eliminate the need of using a boost converter during  
cold crank conditions. Because of these features,  
these devices are well-suited in power supplies for  
various automotive applications.
