The AMS1117 Voltage Regulator Module (3.3V / 5V) is a compact and reliable power regulation solution designed to provide stable voltage output for microcontrollers, sensors, and other electronic devices. Based on the AMS1117 linear regulator IC, this module can step down higher DC voltages to either 3.3V or 5V, depending on the module version.
It is widely used in Arduino, ESP8266, ESP32, and Raspberry Pi projects where a clean and regulated power supply is essential for reliable operation. The onboard AMS1117 ensures low dropout performance, stable output, and easy integration with DIY electronics and embedded systems. Its small PCB form factor allows easy use on breadboards and custom circuits.
Key features include:
- Voltage Regulation Options: Available in 3.3V or 5V versions
- Input Voltage Range: Typically 4.5V to 12V DC (varies by load)
- Output Current: Up to 800mA (depending on heat dissipation)
- Low Dropout Regulator (LDO): Ensures stable performance with small input-output voltage differences
- Compact & Breadboard Friendly: Easy to use in DIY and prototyping projects
- Built-in Capacitors: Provides stable voltage with reduced ripple
Applications:
- Power supply for Arduino, ESP8266, ESP32, and Raspberry Pi
- Regulated supply for sensors and modules
- DIY electronics and prototyping
- Robotics and embedded projects
- Voltage regulation in battery-powered systems
