AMS1117 1.2V POWER SUPPLY MODULE DC DC
AMS1117 based 1.2V DC power supply module providing stable low-voltage output for embedded systems and electronic projects.
The AMS1117 1.2V Power Supply Module is a compact and reliable DC voltage regulator module designed to provide a stable 1.2V DC output from a higher input voltage. Based on the AMS1117 low-dropout (LDO) voltage regulator, this module is ideal for powering low-voltage digital ICs, sensors, and microcontroller cores that require a precise 1.2V supply.
The module supports DC input typically from 4.5V to 12V (model dependent) and includes onboard filter capacitors for improved stability and noise reduction. Its simple design, small footprint, and easy pin access make it suitable for Arduino, ARM, FPGA, DSP, and embedded electronics projects, as well as for prototyping and lab use.
