Key Features
- Stable 3.3V Output: Clean, regulated 3.3V supply with +/-1% accuracy - safe for ESP8266, ESP32, STM32, and other 3.3V ICs.
- Low Dropout Design: Only ~1.1V dropout means efficient regulation even from a 4.5V input source.
- Up to 800mA Output: Sufficient current for most microcontroller boards, wireless modules, and sensor arrays.
- Ready-to-Use Breakout: Onboard decoupling capacitors and power LED - no additional external components needed for basic use.
- Built-In Protection: Thermal shutdown and internal current limiting prevent damage from overload or short circuits.
- Breadboard-Friendly: Compact form factor with standard pin headers fits directly into breadboards and perfboards.
- Wide Input Range: Accepts 4.5V to 12V input, making it compatible with USB 5V, 9V batteries, and 12V adapters.
Why Choose This?
- 100% authentic AMS1117-3.3 IC from trusted suppliers - no counterfeit components
- Pre-assembled module with filtering capacitors saves time and reduces wiring errors
- 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse across India
- Expert technical support for circuit design and integration guidance
- Proven reliability used in thousands of commercial and hobbyist designs worldwide
How It Works
The AMS1117-3.3 is a low-dropout linear voltage regulator that converts a higher DC input voltage (4.5V-12V) into a steady 3.3V DC output. The module includes input and output ceramic/electrolytic capacitors for stability and ripple rejection. Simply connect your input power to VIN and GND, and take the regulated 3.3V from the VOUT pin. The onboard LED confirms the module is powered and regulating correctly.
Common Connections
| Module Pin | Connection |
| VIN | Positive terminal of input supply (4.5V-12V DC) |
| GND | Common ground (shared between input and output) |
| VOUT | Regulated 3.3V output to your circuit/load |
Project Ideas
- ESP8266/ESP32 Power Supply: Provide a clean, stable 3.3V rail to Wi-Fi and Bluetooth modules directly from a 5V USB source or battery pack.
- Arduino-to-3.3V Sensor Interface: Step down Arduino's 5V to safely power 3.3V sensors like BME280, BMP180, MPU6050, or OLED displays.
- Breadboard Power Rail: Create a dedicated 3.3V power bus on your breadboard for rapid prototyping with mixed-voltage components.
- Raspberry Pi Pico Companion: Supply regulated 3.3V to peripheral circuits and external modules connected to the Pico.
- Battery-Powered IoT Nodes: Regulate voltage from a 9V battery or Li-ion pack to power low-power wireless sensor nodes in the field.
- Logic Level Shifting Circuits: Use as a reference 3.3V supply alongside 5
