Here’s a snip from p.

There is another possibility To get around this problem low dropout regulators were developed. The acceptable range of ESR plotted versus load current is shown in the graph below. It can accept input voltages from 5. I will try it with the additional cap. In order ratasheet maintain a stable 12 Volt output, an lm294ooct 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.

Thank you for all the input. A voltage regulator is a device which takes an input voltage and outputs a stable fixed voltage. That would work alright. I haven’t experienced it personally, but you could have an issue there that might datasneet in overheating.


Hello, All I have is a cap between the output and ground at 22uf. Comments 10 Comments sorted by Date Added Votes. If you need a low dropout voltage regulator which can be adjusted to give a non-standard voltage in the range 5 to 15 Volts DCclick here to read our new article LM 1 Amp Low Dropout Adjustable Regulator. This makes them perfect for use with 12 Volt lead acid batteries. Quick Links Categories Recent Discussions. For the more commonly required voltages of 3.


Unfortunately the regulators mentioned above have quite a high voltage drop — typically up to 3 Volts. Many 12V-rated devices can be damaged by being exposed to voltages in excess of 12 Volts — particularly LED lights which have a maximum working voltage typically of It runs on 12 Volts and with 1 camera the drain will be about 2 Amps max.

The only things being powered in the circuit is the stamp and the LCD.

Ideally a lead acid battery should never be allowed to get below dayasheet Is ths just because of the load placed on it due to the lcd? Friday, December 05, Do you know about how much output current you have? Below is a diagram showing the three legs of the LM — one datadheet the input voltage, one for the output voltage, and one for the ground:. When under charge, the voltage can easily get over 14V — sufficient to cause damage to sensitive 12V equipment.

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.

Rapid electronics sell the 3 and dataseet. Groups is subject to http: The unit will be on float charge with a 85 Ah battery so being able to have battery backup, but I hope this extra information on the above regulators is of help. Check your caps, it might be leaky.

This is the 12 Volt one I put together. Click here now to find out more about or to buy either LT 7.

Basic Stamp List Subject: I believe the data sheets show a 0. The burn your finger kind of hot. The LMCT range has internal short circuit and thermal overload protection, so datadheet need to make a special effort to damage one.

Sign In or Register to comment. It can output up to 1 Amp at a fixed 12 Volts DC with a dropout of just 0.

Larger values of output capacitance will give improved transient response. Hi John, What is the input voltage to the regulator — can you measure it? Your use of Yahoo! I can’t find a schematic of it. The LM gets hot after a few min which isn’t nice. Click here to view these low drop out regulators now. Should I use some other voltage regulator? Also, remember the more voltage you have to drop and the more current you want to pull, the hotter the device will run.

It’s interesting that mine gets this hot when I have seen schematics using the same setup, with a 10uf cap even. If you need a 12 Volt voltage regulator to supply more than 1 Amp of current to power an LCD television, laptop, or large amount of lighting, then take a look at our article on the Amperor ADPDC
