DESCRIPTION  
The TPS798xx is the first device in a line of 50-V high-voltage micropower low-dropout (LDO) linear regulators.  
This device is capable of supplying 50-mA output current with a dropout voltage of only 300 mV. Designed for  
low quiescent current high voltage (50 V) applications, 40 μA operating and 1 μA in shutdown makes the  
TPS798xx an ideal choice for battery-powered or high-voltage systems. Quiescent current is also well-controlled  
in dropout.  
Other features of the TPS798xx include the ability to operate with low equivalent series resistance (ESR) ceramic  
output capacitors. This device is stable with only 1 μF on the output; most older devices require between 10-μF  
and 100-μF tantalum capacitors for stability. Small ceramic capacitors can be used without the necessary  
addition of ESR, as is common with other regulators. Internal protection circuitry includes reverse input-battery  
protection, reverse output current protection, current limiting, and thermal limiting to protect the device in various  
fault conditions.  
This device is available in a fixed output voltage of 5 V (TPS79850) and with an adjustable output voltage with a  
1.275-V reference voltage (TPS79801). The TPS798xx regulator is available in a 8-lead MSOP (DGN) package  
with an exposed pad for enhanced thermal management capability.
