TPS793285DBVR TI LDO Regulator | SOT-23-5 | 2.85V Output, 200mA

Product Overview

The TPS793285DBVR from Texas Instruments is a low-dropout (LDO) linear regulator designed for precision voltage regulation in space-constrained applications. Housed in a compact SOT-23-5 package, this device delivers a fixed output voltage of 2.85V with a maximum output current of 200mA. It features ultra-low dropout voltage, high power-supply rejection ratio (PSRR), and low noise, making it ideal for noise-sensitive analog and RF circuits. The TPS793285DBVR operates over a wide input voltage range from 2.7V to 5.5V, ensuring compatibility with common battery and system rails. Its enable pin allows for power sequencing and shutdown control, reducing quiescent current to near zero when disabled.
