The LD1117S33TR is a low-dropout voltage regulator capable of providing up to 800mA of output current with a fixed 3.3V output voltage. It operates with a very low dropout voltage, typically 1V at full load, ensuring efficient power conversion even when the input voltage is close to the output voltage.


  • Low Dropout Voltage: Typically 1V at 800mA load.
  • Fixed Output Voltage: 3.3V, suitable for powering microcontrollers, sensors, and other 3.3V devices.
  • High Accuracy: Output voltage tolerance within ±2% over the temperature range.
  • Current Limit Protection: Built-in current limit and thermal shutdown protection ensure safe operation under various conditions.
  • Small Package: Available in compact SOT-223 package, suitable for space-constrained applications.
  • Wide Operating Temperature Range: Supports operation from -40°C to +125°C, making it suitable for industrial and automotive applications.

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
