7 Detailed Description

7.1 Overview

Designed to meet the needs of sensitive RF and analog circuits, the LP5907-Q1 provides low noise, high PSRR,

low quiescent current, as well as low line and load transient response figures. Using new innovative design

techniques, the LP5907-Q1 offers class leading noise performance without the need for a separate noise filter

capacitor.

The LP5907-Q1 is designed to perform with a single 1-µF input capacitor and a single 1-µF ceramic output

capacitor. With a reasonable PCB layout, the single 1-µF ceramic output capacitor can be placed up to 10 cm

away from the LP5907-Q1 package.
