AMS 1117 5V Step Down Power Supply Module

Description

The AMS1117 5V Module is a small, ready-to-use power supply board that simplifies using the popular AMS1117-5.0 linear voltage regulator IC.¹

 Core Function & Features

Voltage Regulation: Its primary function is to convert a higher DC input voltage into a stable, fixed 5V DC output.² It is a step-down (buck) regulator.³

LDO (Low Dropout): The AMS1117 is a Low Dropout Regulator (LDO), meaning it can maintain a stable 5V output even when the input voltage is only slightly higher (e.g., ⁴$6.5 \text{V}$).⁵

Input/Output: It typically accepts an input voltage range of ⁶$6 \text{V}$ to ⁷$12 \text{V}$ and provides a stable ⁸$5 \text{V}$ output with a maximum current of around ⁹$0.8 \text{A}$ to ¹⁰$1 \text{A}$.¹¹

Convenience: The module format includes the necessary filter capacitors and convenient header pins (often ¹²$0.1”$ pitch), making it breadboard-friendly and easy to integrate into DIY electronics and prototyping projects.¹³
