If you must test: But a toaster, a radio, and a PC are all “boxes with wall-plugs”, yet not the same thing.

Now measure 5V from Out to Gnd.

It is not necessary to bypass the output, although this does improve transient response somewhat. As a first approximation, the diode does not turn on at all, should read OL infinity. That was a Clue.

Get the polarity right!! The first regs had 14 or 8 pins and may have needed an external transistor such as your 2N to handle big loads. I understand wanting to test. While PCs usually don’t have bread-slots, with transistors and regulators you gotta go by the part number. Input bypassing is needed, however, if the regulator is located very far from the. I’m going to research what the hell voltage regulators are and how they work so I don’t make a similar mistake down the road.

The LMK is complete 5V regulator fabricated on a single silicon chip. Note that the battery has to hold at least 7V into the part, because the minimum In-Out voltage is 1.


LM309K – LM309 5V 1A Voltage Regulator Datasheet

Making some random assumptions about the side of diodes in a ‘, I get a number like a few million Ohms. This divides the output to the same voltage as the internal reference.

A simple reg would include a voltage reference Zenera lm3009k transistor to compare that reference to the output voltage, and a big transistor to pass the correct amount of power through. Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic.

However there may be a few million Dtaasheet of internal leakage in a large part. Current limiting is included to limit the peak output current to a safe value. However you bought from a very reputable source, reputable chips have defect rates below 1 in a lm3099k, you can just assume the parts are good until you wire them up and check ALL other possible errors. If forward across a diode they read about half-scale on all ranges.

The devices are available in the TO3 power package. Haha, okay, well that explains the weird readings then! Is this right for this transistor???

Input bypassing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. They could still be a break inside the plastic– a barely-not-rejected batch of plastic might have millions-Ohm leakage between pin stubs.

This is “too small for real work” but can be detected by many meters. Thanks so much for your help!!!! Okay, well thanks very much for clarifying that! A voltage regulator is several transistors working together.

On some regs this is plain simple resistance, no diodes. The regulators are essentially blow-out proof. The available output current is greater than 1A. With a heat sink, the effective thermal. He is designed for local regulation on digital logic cards, eliminating the distribution problems associated with single-point regulation. For these transistors, brand new from Jameco, do these ‘s look right? Stability is also achieved by methods that provide very good.

Regulators are a specific complete function and the pin names make some sense. If internal dissipation becomes too great, the regulator will shut down to prevent excessive heating.

Operating Junction Temperature Range.

I ordered several transistors for each model and they all behave the same way, which leads me to believe they are “right” Wiring errors always exceed parts problems. For the LMK I’m not sure which is which, the data sheets only shows input emitter? So here’s my question. I’m testing them to make sure I’ve got the correct pinout and they work properly. Again, I’m new to all this, but it doesn’t seem right.
