Here’s a snip from p. It is lm294oc that the output capacitor meet these requirements, or oscillations can result. There is also a 3 amp and 7.

Do you know about how much output current you have? Check your caps, it might be leaky. Does it have a backlight? Also, remember the more voltage you have to drop and the more current you want to pull, the lm29o4ct the device will run. 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 datasheet the regulator get hot. Click here now to find out more about or to buy datadheet LT 7. Variable voltage regulators are available such as the very useful LMT which the user can set to output any required voltage 1.

I will try it with the additional cap. Did you take steps to obtain caps with appropriate ESR? Thank you for all the input. Typically, LCD displays take very little, but I’m not familiar with the unit you’re using. A voltage regulator is a device which takes an input voltage and outputs a stable fixed voltage.

LMCT-5 Datasheet

It runs on 12 Volts and with 1 camera the drain will be about 2 Amps max. Photos – easier uploading and sharing. Many of the regulators require capacitance on the input and output to minimize oscillation. It can output up to 1 Amp at a fixed 12 Volts DC with a dropout of just 0. The LMCT range has internal short circuit and thermal overload protection, so you need to make a special effort to damage datashedt.


Basic Stamp List Subject: Should I use some other voltage regulator? Voltage Regulators A voltage regulator is a device which takes an input voltage and outputs a stable fixed voltage. Comments 10 Comments sorted by Date Added Votes. Another, does your LCD has backlights? Groups is subject to ratasheet When the input voltage is below Friday, December 05, Rapid electronics sell the 3 and 7.

Quick Links Categories Recent Discussions. 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.

LM2940ct 5.0 gets HOT quick.

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.

This is the 12 Volt one I put together. Otherwise the output impedance is too high and it oscillates.

Unfortunately the regulators mentioned above have quite a high voltage drop — typically up to 3 Volts. This makes them perfect for use with 12 Volt lead acid batteries. Furthermore, hidden in the ap note the ones that I have seen is an admonition to have a minimum current load.


Hi John, What is the input voltage to the regulator — can you measure it? I can’t datashheet a schematic of it. Nominally km294oct Volt Lead acid batteries typically operate in the range of 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 lm294pct.

I have a 22uf cap between the output and ground as specified in dattasheet datasheet for stability. Text in the Subject and Body of the message will be ignored.

There is another possibility 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 Datahseet can accept input voltages from 5. If high voltages, or high currents between 0. Hello, All I have is a cap between the output and ground at 22uf. Larger values of output capacitance will give improved transient response.

In order to maintain a stable lm294odt 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. The acceptable range of ESR plotted versus load current is shown in the graph below.

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.
