TPS77516PWPR

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

The TPS77516PWPR is a fixed-output low-dropout voltage regulator from the TPS775xx family, manufactured by Texas Instruments. It provides a nominal output voltage of 1.6 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range of 2.7 V to 10 V and features a typical dropout voltage of 169 mV at full load. It incorporates an open-drain power-on reset output with a 200 ms delay. The component utilizes a PMOS pass element for ultralow quiescent current consumption and is housed in a 20-pin PowerPAD HTSSOP package.
