Question about the LD voltage regulator | All About Circuits
Nov 29, 54 0. I’m connecting it to a 15V supply a GAIA converter and, quite obviously, it generates lots of heat and sometimes shuts itself down.
The only peripherals I added are a couple of capacitors, like in the datasheet’s typ. Anyway, main question is how to reduce the heat with minimal peripheral additions I want to keep the prototype board very clean from various glues and wires. Maybe a simple heatsink will do the job? Also, as far as Dztasheet understood the has an adjustable version, so can I use two resistors to get 5V from the adjustable datashet of this regulator LDV without generating a lot of heat?
Is there a better regulator sold in the same package with the same pin configuration? If you feel like giving any additional advise, please do DS: Dec 31, 2.
Question about the LD1086-50 voltage regulator
Jul 17, 22, 1, If it’s getting hot with just capacitors attached, you have a problem. Perhaps your caps are shorted internally, or you connected the regulator incorrectly.
There’s really no getting around that when you’re using a linear regulator. A datashet dropout regulator doesn’t do you any good if you’re supplying it with a high voltage – it’ll still dissipate a lot of heat.
Dec 31, 3. Thanks for the quick reply! Do you see any good way to at least reduce the level of heat?
Perhaps even gluing an additional regulator somehow in-between? Maybe using a different regulator? Dec 31, 4. Nov 28, Jan 1, 5.
Giving your regulator an input voltage of 6v to 7v would eliminate most of the heating. One way to do that would be to use a switching regulator between your 15v supply and your LDO regulator. This could be very efficient, but will generate a lot of electrical noise if not designed and built carefully. datqsheet

A “brute force” method would be to simply use a series of fixed resistors or one heavy-duty rheostat between your 15v supply and your LDO regulator input. This can easily cause your voltage regulation to be very poor if the load is dynamic, or the regulator to shut down if the correct resistance is not selected.
