AMS1117 3.3V Linear Voltage Regulator Module (SOT-223 / Power Step-Down) (5piece)

The AMS1117 3.3V Step-Down Voltage Regulator is a compact, high-efficiency Low Dropout (LDO) linear regulator designed to deliver a stable 3.3V DC output from a higher input voltage source (up to 12V). Capable of providing up to 800mA of current, it is ideal for powering microcontrollers, sensors, Wi-Fi modules (ESP8266/ESP32), and DIY electronic projects requiring clean, reliable 3.3V power.

• Stable 3.3V Output: Features an integrated linear voltage regulator with built-in thermal and current overload protection.

• Plug & Play Module: Pre-soldered with dual-row 2.54mm header pins for easy breadboard and PCB integration.

• Onboard Power Indicator: Includes an LED light to instantly verify power supply status.

• Broad Input Range: Accepts DC input voltages from 4.5V to 12V, efficiently stepping down to 3.3V.

• Microcontroller Ready: Perfectly suited for powering 3.3V electronics like ESP8266, ESP32, STM32, Raspberry Pi sensors, and Arduino modules.

Typical Applications

• Powering 3.3V sensors, displays, and Wireless Modules (NRF24L01, ESP8266).

• Breadboard prototyping & hobbyist DIY electronics.

• Microcontroller power supply (Arduino, ESP32, STM32, PIC).

• Battery-powered electronic device regulation.
