Above 12V plus a bit it will provide 12V out and will be called upon to dissipate a lot of power perhapsand below 12V plus the dropout voltage down to a few volts it will provide the input voltage less a small drop, typically. It’s saved me hours of time! To prevent you pulling even more hair out, take a look at this calculator and the associated table of voltages available using standard resistors.
Unfortunately OP does not mention one very important parameter value which prevents me from suggesting a practical design. Here’s the datasheet for the KAR12C: Maybe ldd33 have the 1.

Sign up using Email and Password. Bimpelrekkie are you implying that one can ever master circuit design? To make it 3. With no Resistor Load, output is 4.

The battery should be 12V and up to 14V when charging. 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.
Are you sure you have the 3. Given a potential part number, the above paragraph can be illustrated with a figure from the datasheet: Use a LD calculator if you want to use different value resistors.
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 currentfeedback input.

Spehro Pefhany k 4 What potential pitfalls are you seeing? I’m trying to design a circuit that will power my 12V LEDs. It is my first question on this site and I’m probably doing something wrong, try to be gentle! It won’t be of any help.
It will provide no more than 12V. Uhm, no, this schematic is pure nonsense. Low-Noise Fixed Voltage Application.
Fixed and adjustable output voltage versions, featuring the reference bypass. Post as a guest Name. Is this schematic feasible?
LD not providing fixed 3. With low Resistor Load 1k Ohm just for the purpose of testing voltage does not keep at 4. How do I identify the version I regulatir
