TPS7N53EVM-138 Evaluation Module
Description
The TPS7N53EVM-138 is designed to help design
engineers evaluate the operation and performance of
the TPS7N53 linear regulator for possible use in a
circuit application. This particular EVM configuration
contains a single low-noise, high accuracy, linear
regulator for a wide range of applications. The
regulator is capable of delivering up to 3A to the
load with low VIN to VOUT dropout voltage. A high
performance load transient circuit is included to assist
the user with high-speed load transient testing. Low
inductive current loops are integrated into the board
to assist the user with input and output current
measurements.
