FEATURES  
DESCRIPTION  
Low Dropout Voltage  
300mV at IOUT = 150mA  
The TPS7A6201 is a low dropout linear voltage  
regulator designed for low power consumption and  
quiescent current less than 25 µA in light load  
applications. This device features an integrated over-  
current protection, and is designed to achieve stable  
operation even with low-ESR ceramic output  
capacitors. The output voltage can be programmed  
using external resistors. 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, this  
device is well suited in power supplies for various  
automotive applications.  
4-V to 40-V Wide Input Voltage Range  
With up to 45-V Transients
