Design files

Overview

The TIDA-00896 reference design provides an easy to implement, low standby current and isolated AC to DC rectification. The AC input voltage is regulated to a ripple free 3.3V using LM2936 a low dropout (LDO) linear regulator. The 3.3V voltage rail is ideal to power microcontrollers which are intended to operate in a low power standby mode most of the time. The low standby quiescent current consumption of LM2936 minimizes the power consumption during the long low power cycles of the system.

Features
  • Low stand by current regulator (IQ < 20uA at 100 µA load)
  • Easy to implement AC to DC rectification and regulation
  • AC grid power to 3.3V regulated DC voltage
  • -30 mV maximum load regulation from nominal output voltage
  • 27 mV> load transient with a 30 mA/10 µs load step
  • 50 mA maximum output current, with short circuit current limit protection
  • Input and transient voltage protection
  • TIDA-00896 provides: design guide, test data and design files for the post AC to DC voltage regulator and ripple cleaner regulator
