Jan 14, Posts: Sun Aug 13, 1: Dattasheet don’t think it’s been suggested but why a 12v adapter If you click through and buy from our affiliate partnerswe earn a small commission.

These capacitors should be placed close to the terminals for them to work effectively. We just need two capacitors of vale 33uf and 0. I played around with the calculator in PHOBoS’ link with the numbers from the heat sink and LM data sheet and the 2W of dissipation sounds about right.

Dedicated to experimental electro-acoustic and electronic music. What do you guys think of this? For example if there is an amplifier in it which is drawing most of the current you might be able to replace that with a 12V one.

Some devices provide slightly different voltages than usual, such as the LM78L62 6. These devices support an input voltage anywhere from around 2.

Wed Nov 01, Please support our site. Without a heatsink it gets easily above C.

3-TERMINAL 1A POSITIVE VOLTAGE REGULATOR

Of course as voltage goes up there are limits to current without heatsinking, although ussual synth stuff can be built this way. A DC-DC converter might indeed not be such a bad idea it’s definitely more efficient, although it could cause some unwanted noise. A datazheet search led me to this page which might be helpful and shows how many variables there are.

Views Read Edit View history. I did try some calculations myself and it depends a lot on the ambient temperature you use. At 9V supply the regulator doesn’t get hot enough to burn you, but still uncomfortably hot with the current heat sink.

This is a typical application circuit of the IC. I don’t want to discourage your exploration with circuit bending, and I’ll say i don’t know how much experience you have with circuitry given your posting here about THIS question and given the very intellectual back and forth you likely know whats up but to any folks still leaning It works, but I measured about mA being drawn from the 6V line, at which the regulator gets too hot to touch very quickly.

In our case the IC is an iconic regulator IC that finds its application in most of the projects. Came up with a heat sink temp of about 40C which would be pretty warm edit: I have no experience with it so can only guess but I would think it is much more effecient and therefor doesn’t get so warm.

January Learn how and when to remove this template message. They can be done with fets instead of bipolars which offer even lower power components. Getting right heatsink seems like more difficult than building good psu, although i found one has to understand only a few basics to get sufficient heatsink.

Usually I just put a heatsink on it and if it gets xatasheet hot to touch I use a bigger one. This article needs additional citations for verification.

I’d say you were bending in dangerous territory. Such circuits work very good for voltages over 40V which can’t be done with ussual regs.

Will the usual cap filters fix that?
