AMS1117 1.5V POWER SUPPLY MODULE DC DC
AMS1117 based 1.5V DC power supply module providing a stable low-voltage output for embedded electronics and prototyping applications.
The AMS1117 1.5V Power Supply Module is a compact and dependable DC voltage regulator module designed to provide a stable 1.5V DC output from a higher input voltage. Built around the AMS1117 low-dropout (LDO) regulator, it is ideal for powering low-voltage ICs, sensors, memory chips, and processor cores that require a precise 1.5V supply.
The module typically accepts a 4.5V–12V DC input (model dependent) and includes onboard filter capacitors for improved voltage stability and reduced noise. Its small size and simple pin layout make it suitable for Arduino, ARM, FPGA, DSP, and general embedded system projects, as well as for prototyping and laboratory use.
