LP5907A33YKMR TI LDO Regulator | 4-DSBGA (0.65x0.65) | 3.3V Output, 250mA

Product Overview

The LP5907A33YKMR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with a maximum current of 250mA. Housed in a compact 4-DSBGA (0.65x0.65) package, it offers excellent line and load regulation, making it ideal for noise-sensitive applications. The device features a low dropout voltage of typically 120mV at full load, enabling efficient operation even with small input-to-output voltage differentials. Its ultra-low output noise (10µVrms typical) and high PSRR (70dB at 1kHz) ensure clean power delivery for analog and RF circuits.
