Description

This linear regulator power solution provides power supply to MSP430 microcontroller. By implementing two linear regulator in parallell but work seperately, this power solution can reduce system power dissipation. Low quiescent current LP5900-3.3 and LP5900-1.8 are fit for this application.

Features
  • Low power dissipation solution
  • Small size solution
  • Cost optimized solution
  • Ripple free and low noise solution
  • TIDA-00691 provides design guide and design files of the power solution
