Scalable, high-current, low-noise parallel low-dropout (LDO) reference design

Overview

TopologyOther Topology
Input voltage0.7-6 V
Output 15 V
IC revisionA

Description

The TIDA-050061 parallel low-dropout (LDO) reference design showcases the TPS7A57 low-noise LDO linear regulator 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 (LDO)
  • TPS7A57EVM-081 EVM supports this reference design

Typical applications

  • Ultrasound scanners
  • Sensor, imaging, and radar
  • Outdoor backhaul units, Active antenna system mMIMO (AAS), Macro remote radio units (RRU)
  • Lab and field instrumentation
