AMS1117-3.3 LDO Regulator 3.3V 800mA Online Bengaluru
AMS1117-3.3 LDO Voltage Regulator ā 3.3V 800mA
The AMS1117-3.3 is a low-dropout linear voltage regulator that converts higher input voltages (up to 15V) into a stable 3.3V output at up to 800mA. Essential for powering microcontroller boards, wireless modules, and sensor networks that require regulated 3.3V logic levels.
Specifications
- Output Voltage: 3.3V Ā±2%
- Output Current: 800mA maximum
- Input Voltage Range: 4.75V to 15V
- Dropout Voltage: 1.1V typical at 800mA
- Package: SOT-223 (3-pin)
- Quiescent Current: 5mA typical
Compatible With
Arduino (5V logic systems), ESP32, ESP8266, STM32 development boards, Raspberry Pi (as secondary regulator), and any circuit requiring stable 3.3V supply from higher voltage sources.
What You Can Build With It
- WiFi/BLE module power conditioning for battery-powered IoT devices
- Sensor protection circuits where 5V to 3.3V step-down is needed
- Stable auxiliary power rails in multi-voltage embedded systems

Frequently Asked Questions
What payment options does Compoden offer?
We accept UPI, debit/credit cards, and Cash on Delivery (COD) for all orders across India.
Where do you ship the AMS1117-3.3?
We ship across India including Delhi, Mumbai, Bangalore, Hyderabad, Chennai, and Pune. Standard shipping takes 2ā4 business days from Bengaluru.
Can I use the AMS1117-3.3 with a 12V power supply?
Yes. The AMS1117-3.3 accepts input voltages from 4.75V to 15V, so a 12V supply works well. Add a 10ĀµF capacitor on the input and output pins for stability.
What's the minimum input voltage for 800mA output?
Minimum input voltage is 4.75V. At 800mA load, ensure input is at least 5.1V (4.75V + 1.1V dropout + margin) for reliable operation.
