Description:
The LD1117 3.3V linear voltage regulator, version TO-220, could give you a constant output voltage of 3.3V from 4V to 15V power supply input, with a 1V linear dropout. That means that you need at least 4.3V input to get 3.3V output.
It converts the 5V power supply to 3.3V for supplying other components. It has a quiescent current draw of 5mA and can provide up to 800mA, using a proper heatsink.
More and more heat occurs as voltage increases.
Without a proper heatsink, this module could burn up to 2W. There is a formula for determining the need for a heatsink related to your power supply input by determining your setup wattage. The formula goes like W = input voltage - 3.3V * average current output(A). Any wattage that goes above 2W would require a heatsink on your setup.
This regulator has an internal current limiting and thermal shutdown protection that makes it the right choice for electronics projects because of its durability.
Package include:
1x Heat sink compound
5x LD1117 – 3.3v
5x Heat sink (2 x 1.5 cm)
5x screw
