Introduction
1.1
TPS715xx Family of LDO Regulators
The TPS715xx family of LDO regulators is comprised of small SOT–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-

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.
