7 Detailed Description

7.1 Overview

Designed to meet the needs of sensitive RF and analog circuits, the TPS7A20 provides low noise, high PSRR,

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

techniques, the TPS7A20 offers class-leading noise performance without the need for a separate noise filter

capacitor.

The TPS7A20 is designed to perform with a single 1-µF input capacitor and a single 1-µF ceramic output

capacitor.
