DYNAMIC WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 2.7–24 V and the output

current range of 0 mA to 50 mA.

Exceeding the specified input range may cause unexpected operation and/or irreversible

damage to the EVM. If there are questions concerning the input range, please contact a TI

field representative prior to connecting the input power.

Applyingloadsoutsideofthespecifiedoutputrangemayresultinunintendedoperationand/or

possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to

connecting any load to the EVM output. If there is uncertainty as to the load specification,

TPS715xx Family of LDO Regulators

1-2 Introduction

1.1 TPS715xx Family of LDO Regulators

TheTPS715xxfamilyofLDOregulatorsiscomprisedofsmallSOT–223/PICO

packaged regulators capable of delivering 50 mA of output current. Features

of the part include:

-50-mA Low-Dropout Regulator

-24-V Maximum Input Voltage

-Low 4.25-µA Quiescent Current at 50 mA

-5-Pin PICO/SC70 (DCK) Package

-Stable With Any Ceramic Capacitor (>0.47 µF)

-Dropout Voltage Typically 100 mV at 50 mA

-Over Current Limitation

-–40°C to 125°C Operating Junction Temperature Range

1.2 EVM Design Strategy

The purpose of this EVM is to facilitate evaluation of the TPS715xx family of

LDO regulators. Each EVM PCB contains a TPS71533 low dropout linear

regulator as well as supporting passive components. Also, the board’s small

size and side clips facilitate attaching it to other PCBs as a power module.
