DESCRIPTION  
•
•
300-mA Maximum Output Current  
Ultralow Quiescent Current  
The TPS7A63xx-Q1 and TPS7A6401-Q1 are a family  
of low-dropout linear voltage regulators designed for  
low power consumption and quiescent current less  
than 35 µA in light-load applications. These devices,  
designed to achieve stable operation even with a low-  
ESR ceramic output capacitor, feature an integrated  
programmable window watchdog and overcurrent  
protection. Designers can program the output voltage  
using external resistors.  
feature allows for a smaller input capacitor and can  
possibly eliminate the need of using boost  
converter during cold-crank conditions. The power-  
on-reset delay is fixed (250 µs typical), or an external  
capacitor can program the delay. Because of such  
features, these devices are well-suited in power  
supplies for various automotive applications.
