Haha, okay, well that explains the weird readings then! Similar results with the LMK. So here’s my question. The Silicon diode hardly turns-on until you get 0. Note that the battery has datassheet hold at least 7V into the part, because the minimum In-Out voltage ml309k 1. Transitors are simple incomplete functions and the pins have abstract names. Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic.

But you buy pre-made regulators so you do not have to think about these things. Input bypassing is needed, however, if the regulator is located very far from the.

LM309K – LM309 5V 1A Voltage Regulator Datasheet

The first regs had 14 or 8 pins and may have needed an external transistor such as your 2N to handle big loads. Honestly I’m not sure how to tell from the data sheet. As a first approximation, the diode does not turn on at all, should read OL infinity. If you must test: Haha So are these readings what you’d expect to see from these components?

Thanks so much for your help!!!! The pm309k plan for ‘ is not so simple, and I can’t identify your 3K at a glance.

However there may be a few million Ohms of internal leakage in a large part. I understand wanting to test. In fact the conductance at 0. Again, I’m new to all this, but it doesn’t seem right.

They could still be a break inside the plastic– a barely-not-rejected batch of plastic might have datasbeet leakage between pin stubs. A simple reg would include a voltage reference Zenera small transistor to compare that reference to the output voltage, and a big transistor to pass the correct amount of power through.

For these transistors, brand new from Jameco, do these ‘s look right? He is designed for local regulation on digital logic cards, eliminating the distribution problems associated with single-point regulation.

Considerable effort was expended to make these devices easy to use and minimize the number of. Now measure 5V from Out to Gnd.

On some regs this is plain simple resistance, no diodes. Tekay Member Halmstad-Sweden Posts: This divides dxtasheet output to the same voltage as the internal reference.

I’m testing them to make sure I’ve got the correct pinout and they work properly. The devices are available in the TO3 power package. All you really proved is that the legs are not broken-off. Input bypassing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. Is this right for this transistor??? That was a Clue. Okay, well thanks very much for clarifying that!

Your 3Meg to 20Meg numbers are close enough.

If internal dissipation becomes too great, the regulator will shut down to prevent excessive heating. The LMK is complete 5V regulator fabricated on a single silicon chip. And this still does not prove that your ‘ can carry the BIG current that you paid the big bucks for.

But a toaster, a radio, and a PC are all “boxes with wall-plugs”, yet not the same thing. Today we use digital meters which mostly only use 0. It is not necessary to bypass the output, although this does improve transient.

It is not necessary to bypass the output, although this does improve transient response somewhat.

Datasheet pdf – http: When you study regulators you will find a couple of resistors out-to-ground. He is designed for local regulation on digital logic cards, eliminating the distribution problems.

This is “too small for real work” but can be detected by many meters. Current limiting is included to limit the peak output current to a safe value. Current limiting is included to limit the peak output.
