Design files

Overview

The TIDA-00533 reference design features a post regulation voltage follower and rail cleaner for noise sensitive applications; provides a high efficiency by operating at the voltage dropout level. This design also offers functional and safety features which make it more beneficial than a discrete rail cleaner.

Features
  • Post-Regulation Rail Ripple Cleaner
  • Adjustable Output Voltage Dropout
  • Output Voltage Disabled Feature
  • Adjustable Soft-Startup
  • Small Foot Print
  • Safety Features: UVLO, output current limiting, over temperature protection
