Part Description
The TPS798xx-Q1 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-Q1 an ideal choice for battery-powered or high-voltage systems. Quiescent current is also well-controlled in dropout. Other features of the TPS798xx-Q1 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 from 10-μF to 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-Q1 regulator is available in a 8-pin MSOPPowerPAD (DGN) package with an exposed pad for enhanced thermal management capability.
