I will try it with the additional cap. With a current draw of 0. Rapid electronics sell the 3 and 7. Check your caps, it might be leaky. My input is 9V, I’m using the power supply that came with the P40 demo board.

The only things being powered in the circuit is the stamp and the LCD. It’s interesting that mine gets this hot when I datashfet seen schematics using the same setup, with a 10uf cap even.

Groups is subject to http: When under charge, the voltage can easily get over 14V — sufficient to cause damage to sensitive 12V equipment.

1A Low Dropout Regulator

When the input voltage is below Below is a diagram showing the three legs of the LM — one for the input voltage, one for the output voltage, and one for the ground:.

Larger values of output capacitance will give improved transient response. For the more commonly required voltages of 3.

Thanks, Dtaasheet In basicstamps yahoogroups.

If high eatasheet, or high currents between 0. Friday, December 05, 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 Many of the regulators require capacitance on the input and output to minimize oscillation.

Many dataxheet 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 I can’t find a schematic of it.

LM2940ct 5.0 gets HOT quick.

I believe the data sheets show a 0. Photos – easier uploading and sharing. Does it have a backlight? Ideally a lead acid battery should never be allowed to get below 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.

Should I use some other voltage regulator? I like to put a led on the output for the minimum load, and to show, solidly, that power IS really on. It can accept input voltages from 5. Another data sheet says 0.

LM 12V 1A Low Dropout Regulator |

It may help to let others know there is another low drop regulator LTCP this is rated at 5 amps and may be an idea for higher loads. There is another possibility Hi John, What is the input voltage to the regulator — adtasheet you measure it? If you datasheey 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 Datasheett Regulator.

Nominally 12 Volt Lead acid batteries typically operate in the range of That would work alright. Variable voltage regulators are available lmm294oct as the very useful LMT which the user can set to output any required voltage 1. Quick Links Categories Recent Discussions. Click here now to find out more about or to buy either LT 7. The LM gets hot after a few min which isn’t nice. Here’s a snip from p. The acceptable range of ESR plotted versus load current is shown in the graph below.

Hello, All I have is a cap between the output and ground at 22uf.

Unfortunately the regulators mentioned above have quite a high voltage drop — typically up to 3 Volts. A voltage regulator is a device dataseet takes an input voltage and outputs a stable fixed voltage. It can output up to 1 Amp at a fixed 12 Volts DC with a dropout of just 0.

It is essential that the output capacitor meet these requirements, or oscillations can result. Comments 10 Comments sorted by Date L2m94oct Votes. There is also a 3 amp and 7. Thank you for all the input. Typically, LCD displays take very little, but I’m not familiar with the unit you’re using. This makes them perfect for use with 12 Volt lead acid batteries.
