Product Introduction

Overview

The LP5907UVX-1.8/NOPB is a low-noise, low-dropout (LDO) linear voltage regulator produced by Texas Instruments. This device is designed to meet the stringent requirements of RF and analog circuits, offering high performance in noise reduction, power supply rejection ratio (PSRR), and low quiescent current. The LP5907 can supply up to 250mA of output current and is available with fixed output voltages, including the 1.8V option in this specific model.

The regulator is stable with 1µF ceramic input and output capacitors and does not require a separate noise bypass capacitor. It features remote output capacitor placement, thermal-overload and short-circuit protection, and operates over a junction temperature range of –40°C to 125°C.
