The LMK is complete 5V regulator fabricated on a single silicon chip. The available output current is greater than 1A. He is designed for. Order Number LMK STEEL or LMK STEEL. See NS Package Number K02A. Order Number LMK See NS Package Number K02C. 2. LMK STEEL/NOPB – Fixed LDO Voltage Regulator, V to 35V, 3mV. Add to compare. Image is Technical Datasheet: LMK STEEL/NOPB Datasheet.
With a heat sink, the effective thermal resistance can only approach the values specified, depending on the efficiency of datasjeet sink. Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic. I understand wanting to test. Your 3Meg to 20Meg numbers are close enough.
Honestly I’m not sure how to tell from the data sheet. I’m testing them to make sure I’ve got the correct pinout and they work properly. Get the polarity right!! Is this right for this transistor??? Haha, okay, well that explains the weird readings then!

I’m going to research what the hell voltage datasjeet are and how they work so I don’t make a similar mistake down the road. If you must test: The regs you buy may have 40 transistors to improve action and reduce abuse little transistor are incredibly cheap.
Input bypassing is needed, however, if the regulator is located very far from the. While PCs usually don’t have bread-slots, with transistors and regulators you gotta go by the part number. Again, I’m new to all this, but it doesn’t seem right. So here’s my question.
LMK STEEL Datasheet pdf – 5-Volt Regulator – National Semiconductor
The available output current is greater than 1A. He is designed for local regulation on digital logic cards, eliminating the distribution problems associated with single-point regulation.
For the LMK I’m not sure which is which, the data sheets only shows input emitter? As a first approximation, the diode does not turn on at all, should read OL infinity. The devices are available in the TO3 power package. The LMK is complete 5V regulator fabricated on a single silicon chip.
Lm309l divides the output to the same voltage as the internal reference. The published plan for ‘ is not catasheet simple, and I can’t identify your 3K at a glance.
On some regs this is plain simple resistance, no diodes. In old days we used Needle Meters which worked from a 1. The regulators are essentially blow-out proof. But you buy pre-made regulators so you do not have to think about these things.
A voltage regulator is several transistors working together. Now measure 5V from Out to Gnd. Considerable effort was expended to make these devices easy to use and minimize the number of external components. Tekay Lm309j Halmstad-Sweden Posts: Transitors are simple incomplete functions and the pins have abstract names. Considerable effort was expended to make these devices easy datashee use and minimize the number of. I ordered several transistors for each model and they all behave the same way, which leads me to believe they are “right” However you bought from a very reputable source, reputable chips have defect rates below 1 in a million, you can just assume the parts are good until you wire them up and check ALL other possible errors.
But a toaster, a radio, and a PC are all “boxes with wall-plugs”, yet not the same thing. Wiring errors always exceed parts problems. Note that the battery has to hold at least 7V datashwet the part, because the minimum In-Out voltage is 1.
LM309K – LM309 5V 1A Voltage Regulator Datasheet
Current limiting is included to limit the peak output current to a safe value. Regulators daatasheet a specific complete function and the pin names make some sense.
In addition, thermal shutdown is provided to keep the IC from overheating. Stability is also achieved by methods that provide very good.
With a heat sink, the effective thermal. That was a Clue.
Haha So are these readings what you’d expect to see from these components? If forward across a diode they read about half-scale on all ranges.
Datasheet pdf – http: Operating Junction Temperature Range. This is “too small for real work” but can be detected by many meters. Okay, well thanks very much for clarifying that! They could still be a break inside the plastic– a barely-not-rejected batch of plastic might have lm3009k leakage between pin stubs. However there may be a few million Ohms of internal leakage in a large part.

And this still does not prove that your ‘ can carry the BIG current that you datasbeet the big bucks for. Current limiting is included to limit the peak output. Thanks so much for your help!!!!
