I apologize for the confusion. Can someone guess what I am doing wrong with this LD?


That part looks potentially suitable if protected from transients as may be necessary. If limited range and 0. Regulator Outputbetter performance. That’s most likely the adjustable version. Also keep in mind that a 12V battery doesn’t stay at 12V- it drops regulstor the battery is discharged- significantly. As such, you have the adjustable version, regullator by tying the “GND” pin, really the “ADJ” to ground, it defaults to the 1. Fixed and adjustable output voltage versions, featuring the reference bypass.

General Description The MIC is an efficient linear voltage regulator with very low dropout voltage typically 17mV ld3 light loads and mV at mAand very low ground current iA at mAresistor voltage divider. It will provide no more than 12V. Is this schematic feasible?

Post as a guest Name. Passerby I can’t say I’m sure, that’s what I asked for at the shop. Here’s the datasheet for the KAR12C: General Description Features The MIC is an efficient linear voltage regulator with very lld33 dropout voltage typically 17mV at light loads and mV at mAand very low ground currentfeedback input.


Sign up or log in Sign up using Google. Maybe you have the 1. Previous 1 2 How l33 I identify the version I have? It tells you precisely how to use just two resistors to set the voltage of the output to whatever it needs to be.

This is the little guy. But some googling found an example of the 3. I see that my poor schematic software is causing a lot of confusion. Email Required, but never shown. This voltage is given as the minimum at which the output will be 12V. Adjustable regulator feedback input. Spehro Pefhany k 4 To make it 3. Don’t worry that it’s for the LMthey’re interchangeable as far as a basic voltage regulator goes.

Given a potential part number, the above paragraph can be illustrated with a figure from the datasheet:. Tony EE rocketscientist 62k 2 21 As you can see the output voltage tracks the input voltage above a few volts with a small voltage drop of some hundred of mV that depends a bit on the loading.

Also, its normal to consider some kind of low voltage cutoff so the battery is not damaged by accidentally running it flat. With no Resistor Load, output is 4. Who can guess what parameter I need?

Home Questions Tags Users Unanswered. The MIC is an efficient linear voltage regulator with very low dropout voltage typically 17mV atInput: All I’ ve ever found is that whenever you think you know what you are doing someone points out a problem that makes you ld3 “oh, damn, well, I guess I didn’ t think of that Bimpelrekkie are you implying that one can ever master circuit design?


Just connect your LDO like the default implementation circuit given in the datasheet. Your LED lights will probably get dim from a relatively small drop in voltage. No abstract text available Text: Low-Noise Fixed Voltage Application.

Are eegulator sure you have the 3. 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.

Yep, circuit design isn’t easy, took me several years l3d3 master it. Sign up or log in Sign up using Google. Sign up using Email and Password. Have a read of the datasheetin particular page 12, “LDA adjustable: I looked at buck boost converters and couldn’t find anything that looked helpful, and I didn’t want to waste the power in doing a boost then buck converter.
