AMS1117 3.3V Power Supply Module
The AMS1117 3.3V power supply module is a compact and efficient voltage regulator module designed to step down higher input voltages (4.5V–12V) to a stable 3.3V output. It is widely used in embedded systems, IoT projects, and microcontroller applications where a reliable 3.3V power source is needed. This module features the AMS1117-3.3 voltage regulator IC, which provides up to 800mA of continuous current with a typical dropout voltage of 1.1V.
Features:
- Input voltage: 4.5V to 12V (Recommended: 5V)
- Output voltage: 3.3V ±1%
- Maximum output current: 800mA
- Regulator IC: AMS1117-3.3
- High efficiency and low ripple voltage
- Compact PCB design for easy integration
- Built-in filtering capacitors for stable output

| Item Type | Voltage Regulator |
| Model | AMS1117 |
| Output Voltage | 3.3 V |
| Max. Input Voltage | 12V |
| Dropout Voltage | 1V |
Applications:
- Powering ESP8266, ESP32, and Arduino modules that require 3.3V
- Step-down conversion from 5V to 3.3V
- IoT, DIY electronics, and embedded systems
Things to Consider:
- The AMS1117 has a dropout voltage of ~1.1V, so it requires at least 4.4V input for a stable 3.3V output.
- If your input voltage is near 3.3V, consider using a low-dropout (LDO) regulator like LM1117 instead.
- For higher current needs (>800mA), use a buck converter instead of an AMS1117 module.
