TPS71247DRCR TI Power Management IC | 10-VSON (3x3) | Dual 300mA LDO, Low Noise

Product Overview

The TPS71247DRCR from Texas Instruments is a dual-output, low-dropout (LDO) voltage regulator designed for applications requiring high performance and small footprint. Each output can deliver up to 300 mA with a low dropout voltage of typically 135 mV at full load. The device offers excellent line and load regulation, low output noise (30 µVrms typical), and high PSRR (60 dB at 1 kHz). It is available in a compact 10-pin VSON (3x3 mm) package, making it ideal for space-constrained designs.
