AMS1117 5V Voltage Regulator – SMD Fixed 5V LDO Regulator for Low-Power Applications
The AMS1117 5V is a compact, fixed Low Dropout (LDO) voltage regulator that provides a stable 5V DC output from a slightly higher input voltage. Widely used in Arduino, ESP8266, ESP32, and other microcontroller-based circuits, this SMD regulator is perfect for space-constrained power supply designs.
 
Key Features:
Fixed 5V Output
Converts input voltage (up to 12V) to a regulated 5V output.
Low Dropout Voltage
Requires only about 1.1V above the output voltage for proper regulation.
SMD Package (SOT-223)
Ideal for compact PCBs, breakout boards, and surface mount applications.
Output Current up to 1A
Can drive low to moderate power loads with sufficient heat dissipation.
Thermal and Overcurrent Protection
Built-in safety features prevent damage under stress or overheating.
 
Applications:
Power supply for Arduino, ESP8266, ESP32
Low-power sensors and modules
DIY electronics and IoT projects
LDO regulator in compact embedded systems
Voltage regulation for SMD PCBs
