Designing LDO

hello,

I am working on designing an LDO (Low-Dropout Regulator) supply circuit. The input voltage is 5V DC, and the required output voltage is 3.3V DC, with a power output of at least 3.3W .

I would appreciate your guidance on planning and sketching the circuit

Thanks for your help.

when you’re supposed to deliver your homework? Just to have a time-reference :slight_smile:

ok, plenty enough to start with some very instructive reading:

I was reading that and still ask for help for this question

This forum is primarily aimed at helping KiCad users with KiCad specific questions, there are other more general electronics forums that are better suited to this kind of question.

Here’s a cheat tip: Search for a LDO regulator IC that can handle a current of, oh you can work this out, and copy a reference circuit from its datasheet. When you have found a circuit and actually want to make a PCB as opposed to breadboarding it, then come back, after reading the Getting Started document. BTW, don’t forget to attach a heatsink to the IC.

Otherwise, as mentioned, designing electronics circuits is outside the scope of this forum.

Ldo datasheet shows examples

LOL… I copypasted the original message verbatim to chatgpt. It gives much to work with.
