Otherwise the output impedance is too high and it oscillates. This is the 12 Volt one I put together. What are the caps on the BS2P40 demo board?

LM2940ct 5.0 gets HOT quick.

The acceptable range of ESR plotted versus load current is shown in the graph below. Basic Stamp List Subject: Check your caps, it might be leaky. Is ths just because of the load placed on it due to the lcd?

Quick Links Datazheet Recent Discussions. There is also a 3 amp and 7. Another, does your LCD has backlights? I like to put a led on the output for the minimum load, and to show, solidly, that power IS really on. There is another possibility Your use of Yahoo! Rapid electronics sell the 3 and 7.

Also, remember the more voltage you have to drop and the more current you want to pull, the hotter the device will run. The burn your finger kind of hot. It runs on 12 Volts and with 1 camera the drain will be about 2 Amps max. Do you know about how much output current you have? Friday, December 05, It’s interesting that mine gets this hot when I have seen schematics using the same setup, with a 10uf cap even.

Thank you for all the input. With a current draw of 0. I haven’t experienced it personally, but you could have an issue there that might result in overheating. I will try it with the additional cap. Variable voltage regulators are available such as the very useful LMT which the user can set to output any required voltage 1.

Another data sheet says 0.

I can’t find a schematic of it. If you aren’t running very much current, and your Vin isn’t too high, a small clip-on heat sink can significantly reduce the regulator’s temperature. Should I use some other voltage regulator?

Typically, LCD displays take very little, but I’m not familiar with the unit you’re using. A low dropout regulator supplies a fixed output voltage with a typical voltage drop of just 0. When the input voltage is below Furthermore, hidden in the ap note the ones that I have seen is an admonition to have a minimum current load.

Photos – easier uploading and sharing. Did you take steps to obtain caps with appropriate ESR? Voltage Regulators A voltage regulator is a device which takes an input voltage and outputs a stable fixed voltage. Unfortunately the regulators mentioned above have quite a high voltage drop — typically up to 3 Volts.

To get around this problem low dropout regulators were developed. The LM gets hot datashest a few min which isn’t nice. I believe the data sheets show a 0. In order to maintain a stable 12 Volt output, an external capacitor of at least 22uF must be used to smooth off the output from the integrated circuit ICwith the capacitor located as close to the IC as possible. Keep in mind lm294occt adapter you have may be putting out more than 9 volts, or may not have a very clean output, both of which will make the regulator get hot.

That would work alright. Here’s a snip from p. For the more commonly required voltages of 3. Does it have a backlight? When under charge, the voltage can easily get over 14V — sufficient to cause damage to sensitive 12V equipment.
