The "Fixed Voltage DC/DC Module 3.3V x 800mA," based on the LM1117T-3.3 voltage regulator, is a compact and efficient electronic solution designed to provide a stable and reliable power source.

This module is capable of receiving an input voltage of up to 20 volts of direct current (DC) and converting it into a precise and constant output of 3.3 volts at a maximum current of 800 milliamperes. This makes it an ideal choice for powering a variety of sensitive electronic components that require a stable reference voltage.

The module features KF301-2P connectors both at the input and output, making installation and connections easy. Additionally, at the output, an additional KF2510-2P connector has been incorporated, further streamlining the connection process.

This device also includes protective measures, such as a 1N4001 diode that safeguards the LM1117T-3.3 regulator from potential voltage spikes. A blue LED diode visually indicates when the module is active, providing a clear operating signal.

To maintain optimal performance, the installation of a TO-220 aluminum heat sink measuring 25x23x16 mm has been provided, helping to maintain a suitable temperature for the regulator and extending the module's lifespan.

In summary, the "Fixed Voltage DC/DC Module 3.3V x 800mA" is a versatile, reliable, and secure electronic solution that meets the needs of those seeking a stable and high-quality power source for their electronic projects.
