TPS7A2025PDQNR TI LDO Regulator | 4-X2SON(1x1) | 2.5V Fixed Output, 300mA

Product Overview

The TPS7A2025PDQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator offering a fixed output voltage of 2.5V with a maximum output current of 300mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), it is designed for space-constrained applications requiring high power-supply rejection ratio (PSRR) and low noise. The device features an enable pin for power sequencing and offers excellent transient response, making it ideal for noise-sensitive analog and RF circuits.
