AMS1117 5V Step-Down Linear Voltage Regulator DC Converter Module
This compact linear voltage regulator module steps down 6.5V to 12V DC input to a stable 5V output, rated for up to 800mA load current. Built around the AMS1117 regulator, it's a practical solution for powering 5V logic from higher DC supplies in Arduino, ESP32, Raspberry Pi, and other microcontroller projects. A red power indicator LED shows when the module is active. The small PCB footprint (8.6mm x 12.33mm) fits easily into tight enclosures or breadboard setups.
Features
• Stable 5V output from 6.5V–12V DC input
• Up to 800mA load current (do not exceed)
• Based on AMS1117 linear regulator
• Red power indicator LED
• Compact PCB size: 8.6mm x 12.33mm
• Input-to-output voltage difference must be ≥1.5V for proper regulation
Compatibility
• Arduino Uno, Nano, Pro Mini (5V )
• ESP32 development boards (5V tolerant peripherals)
• Raspberry Pi (5V power rail extensions, USB power)
• 5V logic sensors and modules
• USB-powered devices (5V rails)
• 5V relay modules, motor drivers
Important Compatibility Note
This is a linear regulator: excess voltage is dissipated as heat. For 12V input at 800mA, the regulator will dissipate ~5.6W — use a heatsink if operating near maximum load for extended periods. Not suitable for stepping down from voltages above 12V without significant thermal management.
Applications
• DIY electronics, Arduino projects, IoT sensor nodes, breadboard power supplies, 5V logic level conversion support, USB device power, portable microcontroller rigs, Raspberry Pi peripherals.
Limitations
• Not designed for medical, life-saving, or life-sustaining equipment
• Not for use in hazardous locations (coal mines, oil depots,.)
• Linear regulation: excess voltage becomes heat — thermal management required at higher loads
• Load current must not exceed 800mA
• Input voltage must not exceed 12V DC
Technical Specifications
• Input Voltage: 6.5V–12V DC (input must exceed output by ≥1.5V)
• Output Voltage: 5V ±5%
• Maximum Load Current: 800mA
• Regulator IC: AMS1117
• PCB Size: 8.6mm x 12.33mm
• Indicator: Red power LED
• Output Voltage Tolerance: ~5% maximum variance
• Applications: DIY electronics, Arduino, ESP32, Raspberry Pi, sensors, USB devices

Frequently Asked Questions (FAQs)
Q: Can I use this with a 12V power supply?
A: Yes, 12V input is within the acceptable range. However, at 800mA load, the regulator will dissipate ~5.6W as heat, so a heatsink is strongly recommended for continuous operation.
Q: Will this power a Raspberry Pi?
A: This module can provide 5V power for Raspberry Pi peripherals or low-power applications drawing under 800mA. For direct Raspberry Pi power, ensure your input source can handle the Pi's peak current demands (typically 2-3A for Pi 4).
Q: Does it need a heatsink?
A: For low current (9V, a small heatsink is recommended.
