Overview
The LP5907UVE-2.8/NOPB is a low-noise, ultra-low-dropout voltage regulator produced by Texas Instruments. This device is designed to supply up to 250mA of output current and is optimized for use in RF and analog circuits. It features low noise, high power supply rejection ratio (PSRR), low quiescent current, and low line or load transient response figures. The LP5907 is available in a DSBGA (YKE) package with 4 pins and operates over an extended temperature range of –40°C to 125°C.
