This 3.3 VDC 100mA Voltage Regulator is in a convenient, 3-Pin TO-92 transistor style package. This is a "Low Dropout" voltage regulator, meaning that it's supply voltage needs to be only 1.7VDC higher than the output voltage, making it useful for all sorts of low power projects.
This voltage regulator has on-board thermal shutdown, short circuit protection and current limiting, making them very hard to destroy accidentally (or intentionally ;) ).


  • Max Input Voltage: 30VDC
  • Output Voltage: 3.3VDC
  • Output Current: 100mA Max
  • Package Size: TO-92
