Overview

The TPS7A57EVM-081 evaluation module (EVM) is a platform for developing the TPS7A57, which is a low-noise, low-dropout (LDO) linear regulator. The TIDA-050061 reference design showcases the TPS7A57 in a parallel configuration using ballast resistors, which is capable of sourcing 13 A.

A high-performance load-transient circuit is included to assist the user with high-speed load-transient testing. Low inductive current loops also are included to assist with input and output current measurements.

Features
  • Load current: 15 A (max)
  • Input voltage range: 0.7 V to 6 V
  • Selectable output voltages: 0.5 V to 5 V
  • VBIAS range: 3 V to 11 V
  • Current-reference and unity-gain low dropout
  • TIDA-050061 design guide supports this EVM
