TPS7A8050DRBR TI LDO Regulator | 8-SON(3x3) | 500mA, 1.5μVrms Noise

Product Overview

The TPS7A8050DRBR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for high-performance applications requiring ultra-low noise and high PSRR. It delivers up to 500 mA output current with a dropout voltage of typically 200 mV at full load. The device operates from an input voltage range of 1.4 V to 6.5 V and provides an adjustable output voltage from 0.8 V to 5.2 V, or fixed output voltages of 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The TPS7A8050DRBR is available in a compact 8-pin SON (3 mm × 3 mm) package, making it suitable for space-constrained designs.
