Product Summary
The TPS79801QDGNRQ1 is a line of 50V high-voltage micropower low-dropout (LDO) linear regulator. The TPS79801QDGNRQ1 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, 40μA operating and 1μA in shutdown makes the TPS79801QDGNRQ1 an ideal choice for battery-powered or high-voltage systems. Quiescent current is also well-controlled in dropout. The applications of the TPS79801QDGNRQ1 include Low-Current, High-Voltage Regulators, and Regulators for Battery-Powered Systems, Telecom, and Automotive.
