Overview

AN734 Vishay Siliconix Design Guidelines for the Low-Noise Low-Dropout Regulator—Si9181 Nitin Kalje INTRODUCTION This application note discusses the operation and features of the Si9181, a 350-mA CMOS low-dropout (LDO), low-noise voltage regulator.
Providing very low ground current to extend battery life, the Si9181 also offers superior line/load transient response and ripple rejection.
Designed to maintain regulation while delivering currents from 0 mA to 600 mA, the Si9181 regulator also features an “out of regulation” error flag signal and ON/OFF control input for complete shutdown.
The Si9181 was designed for applications requiring a regulated voltage equal to or less than the volta...
