LP5900SD-3.3/NOPB TI LDO Regulator | 6-WSON (2.2x2.5) | 3.3V Output, 150mA

Product Overview

The LP5900SD-3.3/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 3.3V with a maximum output current of 150mA. Housed in a compact 6-WSON (2.2x2.5mm) package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). Its ultra-low dropout voltage (typically 80mV at 150mA) ensures efficient operation even with small input-to-output voltage differentials. The LP5900SD-3.3/NOPB is ideal for powering sensitive analog and RF circuits in portable and battery-powered devices.
