With low Resistor Load 1k Ohm just for the purpose of testing voltage does not keep at 4. It will provide no more than 12V. I’ve been looking at and making circuits for almost 30 years now.

It is my first question on this site and I’m probably doing something wrong, try to be gentle! Given a potential part number, the above paragraph can be illustrated with a figure from the datasheet:. All I’ ve ever found is that whenever you think you know what you are doing someone points out a problem that makes you go “oh, damn, well, I guess I didn’ t think of that Yes have a look at the datasheet st.
That’s most likely the adjustable version.

With no Resistor Load, output is 4. Don’t worry that it’s for the LMthey’re interchangeable regulato far as a basic voltage regulator goes. Use a LD calculator if you want to use different value resistors.
The maths involved isn’t very difficult, but I do find that I’m always fighting a losing battle of what resistors I need vs. Sign lv33 using Facebook. Error flag indicates undervoltage fault High output voltage accuracy Guaranteed. Sign up or log in Sign up using Google.
This is the little guy. If you set up an appropriate LDO regulator with 12V out it alone will do what you want.
That part looks potentially suitable if protected from transients as may be necessary. Unfortunately OP does not mention one very important parameter value which prevents me from suggesting od33 practical design.
The actual solution to OP’s problem can be quite easy. As such, you have the adjustable version, and by tying the “GND” pin, really the “ADJ” to ground, it defaults to the 1. It also helps that as I get older I have simply seen more things than others do so simply staying at it circuit design helps as you get more regulatir by the years.
Tony EE rocketscientist 62k 2 21 Your LED lights will probably get dim from a relatively small drop in voltage. I see that my poor schematic software is causing a lot of confusion. No numbers after a regulator part number is a very good indicator that you have an adjustable version. General Description Features The MIC is an efficient linear voltage regulator with very low dropout voltage typically 17mV at light loads and mV at mAand very low ground rsgulatorfeedback input.
Assumed specssince incomplete given: Just connect your LDO like the default implementation circuit given in the datasheet.
