AMS1117 3.3V Power Supply Module

A compact and reliable voltage regulator module based on the AMS1117-3.3V LDO (Low Dropout) regulator IC. This module converts a higher DC input voltage (4.5V-12V) to a stable 3.3V output, making it ideal for powering 3.3V microcontrollers, sensors, Wi-Fi modules (like the ESP8266/ESP32), and other low-voltage logic circuits. Available at The Engineer Store, Bengaluru - with fast shipping, 7-day warranty on manufacturing defects, and dedicated technical support.

Specifications

Key Features

• Stable 3.3V Output: Delivers a clean, regulated 3.3V supply from input voltages up to 12V, ensuring safe and consistent power for sensitive 3.3V devices.
• Low Dropout (LDO) Design: Only requires ~1.1V above the output voltage to regulate properly, so it works efficiently even with a 4.5V input source.
• 800mA Output Current: Sufficient to power ESP8266, ESP32, STM32, LoRa modules, SD card modules, and multiple sensors simultaneously.
• Noise-Free Linear Regulation: Unlike switching regulators, the AMS1117 produces no switching noise - critical for analog sensors, ADC circuits, and RF modules.
• Onboard Filter Capacitors: Pre-soldered input and output decoupling capacitors for stable operation right out of the box.
• Power Indicator LED: Onboard LED confirms the module is powered and regulating correctly.
• Ultra-Compact Form Factor: Tiny PCB that fits easily on breadboards, inside enclosures, or soldered directly into custom PCBs.
• Breadboard Friendly: Standard 2.54mm pitch header pins plug directly into breadboards and prototyping boards.
• Built-In Protection: The AMS1117 IC includes internal thermal shutdown and current limiting to protect against overheating and overcurrent conditions.
