LP5907SNX-4.5/NOPB TI LDO Regulator | 4-X2SON(1x1) | 4.5V Fixed Output, 250mA

Product Overview

The LP5907SNX-4.5/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 4.5V with a maximum output current of 250mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), it is designed for space-constrained applications requiring high accuracy and low noise. The device features a low dropout voltage of typically 120mV at full load, enabling efficient operation even when the input voltage is close to the output. With a quiescent current of only 25µA (typical), it is ideal for battery-powered devices. The LP5907SNX-4.5/NOPB also includes thermal shutdown and current limit protection, ensuring reliable performance under fault conditions.
