Product: AMS11173.3 Voltage Regulator Module (autoplaza) Key benefits Provides a stable, fixed 3.3V supply for circuits that require lowvoltage logic. Simple 3pin singlerow header and compact dualpanel design make wiring quick and spaceefficient. Builtin overtemperature and overload shutdown protects your project from damage and simplifies system safety. Delivers up to 0.8 A of output current for sensors, MCUs, and peripheral modules. Function and performance Regulator type: AMS11173.3 positive fixed voltage regulator module. Input voltage: DC 4.75–12 V. Note: the regulator requires the input to be approximately 1.2 V higher than the 3.3 V output for normal operation. Output: fixed 3.3 V, up to 0.8 A current. Protection: overheat shutdown and overload protection for safer operation. Temperature ratings: operating junction 40 to 125 °C; storage 65 to 150 °C; soldering temperature 265 °C (25 seconds). Installation and connection Before use, inspect the product pictures for the wiring diagram and follow the pin labeling. Connect input and output via the 3pin singlerow header: VIN, GND, VOUT (confirm pin from the product images). Ensure VIN meets the module's input range and is at least 1.2 V above the 3.3 V output for reliable regulation. Mount and solder per your assembly practices; observe the stated soldering temperature limit. Compatibility and use cases Compatible with: Arduino MEGA2560, MSP430 development boards, 3.3 V lowpower MCUs, FPGA/CPLD/PLD systems, ARM7/ARM9/ARM11, STM32, and similar platforms. Example applications: Powering 3.3 V sensors, wireless modules, and peripherals in an MCU development board or prototype. Supplying stable 3.3 V to FPGA/CPLD modules during bench testing or development. Integrating into embedded system projects that require a compact regulator module with thermal and overload protection. What makes it practical Easy to integrate into breadboard or PCBbased projects via the 3pin header. Compact dualpanel layout saves space while keeping connections accessible. Builtin safety features reduce the need for additional protection circuitry.
