This compact 5V voltage regulator module uses the AMS1117-5.0 chip to deliver stable 5V output from unregulated DC sources (7–12V). Ideal for powering Arduino, sensors, and microcontrollers, it features overheat/overcurrent protection and requires minimal external components.
Key Benefits
✔ Stable Output – Fixed 5V ±2% accuracy
✔ Built-in Protections – Thermal shutdown, current limiting
✔ Space-Saving – Ultra-compact PCB design
✔ Low Dropout – Operates down to 1V input-output differential
