Product Introduction

Overview

The LP5907UVX-2.85/NOPB is a 250-mA, ultra-low-noise, low-IQ linear voltage regulator produced by Texas Instruments. This device is designed to meet the stringent requirements of RF and analog circuits, offering low noise, high power supply rejection ratio (PSRR), low quiescent current, and low line or load transient response figures. The LP5907 is particularly suited for applications where noise performance is critical, such as in mobile phones, tablets, digital cameras, and other portable and battery-powered equipment.
