TPS79425DGNT TI LDO Regulator | 8-HVSSOP | 250mA, 3.3V Output

Product Overview

The TPS79425DGNT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for applications requiring high output accuracy and low noise. It delivers up to 250 mA of output current with a fixed output voltage of 3.3 V. The device operates with a very low dropout voltage of typically 120 mV at full load, making it suitable for battery-powered systems. The TPS79425DGNT is offered in a compact 8-pin HVSSOP package, ideal for space-constrained designs.
