LP5951MF-2.8/NOPB TI LDO Regulator | SOT-23-5 | 2.8V Output, 150mA

Product Overview

The LP5951MF-2.8/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It provides a fixed output voltage of 2.8V with a maximum output current of 150mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP5951 features a low quiescent current of 1 µA in shutdown mode and 25 µA in active mode, making it suitable for battery-powered devices. Its wide input voltage range of 2.5V to 5.5V allows operation from various power sources, including single-cell Li-Ion batteries.
