78xx Voltage regulator

Post date: Feb 16, 2016 6:51:47 AM

This big chunky regulator will help you get your 7-35V battery or wall adapter down to a nice clean 5.0V with 2% regulation. Perfect for just about all electronics! This is the TO-220 version, with up to 1.5A current capability, and has internal current limiting + thermal shut-down protection which makes it sturdy and pretty much indestructible - at least electronics-wise (we're pretty sure a hammer might work...)

This regulator has a ~2V linear drop-out. That means you must give it at least 7V to get a clean 5V out. There is a constant 'quiescent' current draw of 6mA.

This regulator can provide up to 1.5A as long as it has proper heat-sinking. The higher your input voltage and output current, the more heat it will generate. Without an extra heatsink, you can burn off up to 2W....
