TPS76528D

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

The TPS76528D is an obsolete ultra-low quiescent current 150-mA low-dropout voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 2.8 V with a maximum tolerance of 3% over specified conditions. The device operates within an input voltage range of 2.7 V to 10 V and supports an output current up to 150 mA. It features a typical dropout voltage of 190 mV at 150 mA and a typical quiescent current of 35 mA. The component includes thermal shutdown protection, an open-drain power-good indicator, and a sleep mode that reduces standby current to less than 1 mA. It is housed in an 8-pin SOIC package.
