I can’t find a schematic of it. Rapid electronics sell the 3 and 7.

LDO Voltage Regulator (5V 1A LM2940CT, drop 0.5V @0.5A)

Hi John, What is the input voltage to the regulator lm294occt can you measure it? Keep in mind the 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.

Here’s a snip from p.

Larger values of output capacitance will give improved transient response. The LMCT range has internal short circuit and thermal overload protection, so you need to make a special effort to damage one.

Friday, December 05, Groups is subject to http: A low dropout regulator supplies a fixed output voltage with a typical voltage drop of just 0. It may help to let others know there is another low drop regulator LTCP this lm2944oct rated at 5 amps and may be an idea for higher loads. 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 Does it have a backlight?


Did you take steps to obtain caps with appropriate ESR? The only things being powered in the circuit is the stamp and the LCD. Text in the Subject and Body ,m294oct the message will be ignored. Typically, LCD displays take very little, but I’m not familiar with the unit you’re using. It can accept input voltages from 5.

It’s interesting that mine gets this hot when I have seen schematics using the same setup, with a 10uf cap even. Do you know about how much output current you have?

The LM gets hot after a few min which isn’t nice.

Thanks, John In basicstamps yahoogroups. The burn your finger kind of hot. When the input voltage is below Another data sheet says 0.

LDO Voltage Regulator (5V 1A LMCT, drop V @A) in Canada Robotix

The acceptable range of ESR plotted versus load current is shown in the graph below. Also, remember the more voltage you have to drop and the more current you want to pull, the hotter the device will run. Nominally 12 Volt Lead acid batteries typically operate in the range of If you need a low dropout voltage dxtasheet 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.

That would work alright. Thank you for all the input. A voltage regulator is a device which takes an input voltage and outputs a stable fixed voltage. What are the caps on the BS2P40 demo board?


In order to maintain a stable 12 Volt output, an external capacitor of at least 22uF must be used dwtasheet smooth off the output from the integrated circuit ICwith the capacitor located as close to the IC as possible. Click here to view these low drop out regulators now.

Hello, All I have is a cap between the output and ground at 22uf. Sign In or Register to comment. I haven’t experienced lm294occt personally, but you could have an issue there that might result in overheating.

Your use of Yahoo! It runs on 12 Volts and with 1 camera the drain will be about 2 Amps max. There is also a 3 ddatasheet and 7. The ESR of the output capacitor will cause loop instability if it is too high or too low. The power in Watts being dissipated within the regulator is the voltage drop across the regulator times the current passing through it. Should I use some other voltage regulator?

I have a 22uf cap between the output and ground as specified in the datasheet for stability. Furthermore, hidden in the ap note the ones that I have seen is an admonition to have a minimum current load. With a current draw of 0. It is essential that the output capacitor meet these requirements, or oscillations can result. Click here now to find out more about or to buy either LT 7.
