TPS799185DDCRG4

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS799185DDCRG4 is a single-output low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 1.8V with a maximum continuous output current of 200mA. The device operates within an input voltage range of 2.7V to 6.5V and maintains a typical quiescent current of 40µA. It features a typical dropout voltage of 100mV at full load, with a maximum specified dropout of 175mV. The regulator offers high power supply rejection ratio (PSRR) performance and includes internal protection mechanisms such as overcurrent limiting and thermal shutdown.
