    Newbie - 12V Regulator Question

    Thanks. very much appreciate your help. I've emailed the company i bought it from to see if i can get the technical datasheet for it.

    Newbie - 12V Regulator Question

    Oh, I will try and see if i can dig up some info about it. but because its a sealed little plastic box with 4 wires coming out of it with a sticker on it that says Input 12Vdc output 3-9v. So by provided voltage under the stated input e.g. 9V instead of 12V does a device with for example no...

    Newbie - 12V Regulator Question

    The thing is that the device says the input is 12vdc but it does run on 9V as I have been running it on a 9V regulator as well for 4 months. Will powering it at lower voltage cause any damage to the device? I am thinking it would either not work with a lower voltage and if it does then it should...

    Newbie - 12V Regulator Question

    Oh that makes sense now. I do not have any more info on the driver its a sealed box that says 12vdc input 3-9v output 1-2W. Definitely doesn't have a regulator inside. way too small to have a regulator as well. So is a safer bet to maybe use a 9V regulator or a 12V low dropout regulator? because...

    Newbie - 12V Regulator Question

    There is no minimum rating on it, the input says 12vdc. but i've run the driver on 9vdc and it works. If my driver draws lets say 400mA current, and i regulate with a 12V regulator that has a 2V dropout. then the lowest it would go to would be 10v which the driver still works with. However...

    Newbie - 12V Regulator Question

    Thanks for your reply Harald. I made a mistake, i am using a TS7812CZ 12V regulator. I understand that this regulator also has a high voltage drop. But the thing is i am using it to power an LED driver which requires 12v or under to drive LED's in parallel which ends up giving a 3.2v output...

    Newbie - 12V Regulator Question

    Thanks for your reply. I used a L7812CV regulator. What will happen if the voltage of the car drops? although the regulator will stop working, wouldnt the regulator then just output whatever is coming in? so for example i'm trying to get 12V or less into my device, and since the car voltage is...

    Newbie - 12V Regulator Question

    Hello, I'm a newbie here, I have a quick question that i'm hoping someone can help me on. I've got a device that needs powering from a car power source and has a 12V max input voltage. It draws 650mA of current. So i've created a little circuit board that consists of the following: IN...
