The AMS1117-3.3V Power Supply Module is a compact voltage regulator module designed to convert a higher DC input voltage into a stable 3.3V output. Based on the AMS1117-3.3 low-dropout (LDO) regulator, it is ideal for powering 3.3V microcontrollers, sensors, and other low-power electronic devices. Unlike a switching regulator, this is a linear regulator, making it suitable for applications requiring low output noise.
Key Features:
✔ Output Voltage: Fixed 3.3V DC
✔ Input Voltage: Typically 4.5V–12V DC (module-dependent)
✔ Output Current: Up to 800mA (depends on input voltage and cooling)
✔ Based on the AMS1117-3.3 LDO Regulator
✔ Low-Dropout Linear Regulator
✔ Compact Module with Input/Output Header Pins
✔ Built-in Thermal Shutdown and Current Limiting
Applications:
🔹 Arduino and ESP32 projects
🔹 Raspberry Pi peripherals
🔹 3.3V sensors and modules
🔹 IoT devices
🔹 Embedded systems
🔹 DIY electronics and prototyping
The AMS1117-3.3V Power Supply Module offers a simple and reliable way to obtain a regulated 3.3V supply for low-power electronics. For applications with large voltage drops or higher currents, a switching (buck) converter is generally more efficient.
