Error flag indicates undervoltage fault High output voltage accuracy Guaranteed. The problem is I can’t get it to provide 3.

Home Questions Tags Users Unanswered. Fixed and adjustable output voltage versions, featuring the reference bypass. To prevent you pulling even more hair out, take a look at this calculator and the associated table of voltages available using standard resistors. Sign up or log in Sign up using Google. Adjustable regulator feedback input.

No numbers after a regulator part number is a very good indicator that you have an adjustable version. 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 Here’s the datasheet for the KAR12C: But some googling found an example of the 3.

There are many potential pitfalls in what you are trying to do- aside from current and heat, the situation you describe implies a vehicle electrical system which has a whole associated set of concerns.

Just connect your LDO like the default implementation circuit given in the datasheet. So I’m getting 5V from Arduino and turning it into 3.

LD not providing fixed 3. With no Resistor Load, output is 4. Also keep in mind that a 12V battery doesn’t stay at 12V- it drops as the battery is discharged- significantly. The actual solution to OP’s problem can be quite easy. Regulator Outputbetter performance.

Can someone guess what I am doing wrong with this LD? Bimpelrekkie are you implying that one can ever master circuit design? Is this schematic feasible? Post as a guest Name.

Unfortunately OP does not mention one very important parameter value which prevents me from suggesting a practical design. Given a potential part number, the above paragraph can be illustrated with a figure from the datasheet: Regulator Output 5 fixed 5 adj. Bruno 50 1 2 6. Maybe you have the regulaator.

Sign up or log in Sign up using Google. It is my first question on this site and I’m probably doing something wrong, try to be gentle!

I’m starting to think that maybe providing 3.

As such, you have the adjustable version, and by tying the “GND” pin, really the “ADJ” to ground, it defaults to the 1.
