The D36V50Fx family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 50 V. Pot Magnets with Cylindrical Borehole Screw-on.Adjustable Step Up / Step Down Power Supplies.
12 V Step Up / Step Down Power Supplies.3.3 V Step Up / Step Down Power Supplies.This regulator does not require capacitors for stability, but we recommend at least 10uF electrolytic capacitors on both input and output. a 9V battery and 1 Amp of average output current means the regulator is burning off (9 - 5)*1 = 4 Watts! This setup would definately need a heat sink! The wattage of your set up is = (InputVoltage - 5V) * AverageCurrentInAmps. We like this calculator for determining your heat sink requirements It's a TO-220 package, so use 62.5☌/Watt junction thermal resistance. Without an extra heatsink, you can burn off up to 2W. The higher your input voltage and output current, the more heat it will generate.
This regulator can provide up to 1.5A as long as it has proper heat-sinking. There is a constant 'quiescent' current draw of 6mA.
That means you must give it at least 7V to get a clean 5V out. This regulator has a ~2V linear drop-out. 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.) Ah the venerable 7805, who amongst us has not used this popular linear regulator? 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.
