说明

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.
