LP5907MFX-4.5/NOPB TI LDO Regulator | SOT-23-5 | 4.5V Output, 250mA

Product Overview

The LP5907MFX-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 SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). With a typical dropout voltage of only 120mV at 250mA load, it ensures efficient operation even with minimal input-to-output voltage differential. The LP5907 series is known for its excellent line and load transient response, making it ideal for powering sensitive analog and digital circuits.
