When the input voltage is below I will try it with the additional cap.

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. With a current draw of 0. Another, does your LCD has backlights? A voltage regulator is a device which takes an input voltage and outputs a stable fixed voltage.

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. If high voltages, or high currents between 0. It runs on 12 Volts and with 1 camera the drain will be about 2 Amps max.

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 The ESR of the output capacitor will cause loop lm94oct if it is too high or too low.


Hello, All I have is a cap between the output and ground at 22uf. This makes them perfect for use with 12 Volt lead acid batteries. Thanks, John In basicstamps yahoogroups.

LM2940 12V 1A Low Dropout Regulator

Quick Links Categories Recent Discussions. Nominally 12 Volt Lead acid batteries typically operate in the range of I can’t find a schematic of it.

Otherwise the output impedance is too high and it oscillates. Hi John, What is the input voltage to the regulator — can you measure it? It can output up to 1 Amp at a fixed 12 Volts DC with a dropout of just 0. What are the caps on the BS2P40 demo board?

LMCT-5 Datasheet

Thank you for all the input. Check your caps, it might be leaky. It can accept input voltages from 5.

lk294oct Another data sheet says 0. The LM gets hot after a few min which isn’t nice. 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 A low dropout regulator supplies a fixed output voltage with a typical voltage drop of just 0.


Comments 10 Comments sorted by Date Added Votes. Larger values of output capacitance will give improved transient response. Variable voltage regulators are available such as the very useful LMT which the user can set to output any required voltage 1. Friday, December 05, If you need a low dropout voltage regulator which can ratasheet adjusted to give a non-standard voltage datasheeet the range 5 to 15 Volts DCclick here to read our new article LM 1 Amp Low Dropout Adjustable Regulator.

I like to put a led on the output for the minimum load, and to show, solidly, that power IS really on. For the more commonly required voltages of 3.

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

Keep in mind the adapter you have lm29oct be putting out more than 9 volts, or may not have a very clean output, both of which will make the regulator get hot. Do you know about how much output current you have?
