LMK NTE Equivalent NTEK VOLTAGE REGULATOR PO – Wholesale Electronics

lm309m The regulators are essentially blow-out proof. Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic. Your 3Meg to 20Meg numbers are close enough. On some regs this is plain simple resistance, no diodes. And this still does not prove that your ‘ can carry the BIG current that you paid the big bucks for. While PCs usually don’t have bread-slots, with transistors and regulators you gotta go by the part number.

If internal dissipation dtasheet too great, the regulator will shut down to prevent excessive heating. Om309k is designed for local regulation on digital logic cards, eliminating the distribution problems. Now measure 5V from Out to Gnd. Today they have simplified down to 3 pins, which means they can use the same “frame” as power transistors. Stability is also achieved by methods that provide very good. For these transistors, brand new from Jameco, do these ‘s look right? November dataseet, Operating Junction Temperature Range.

Input bypassing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. In fact the conductance at 0.

Current limiting is included to limit the peak output. As a first approximation, the diode does not turn on at all, should read OL infinity. In addition, thermal shutdown is provided to keep the IC from overheating.

Transitors are simple incomplete functions and the pins have abstract names. All you really proved is that the legs are not broken-off. Thanks so much for your help!!!! Is this right for this transistor??? He is designed for local regulation on digital logic cards, eliminating the distribution problems associated with single-point regulation.

Similar results with the LMK. Today we use digital meters which mostly only use 0.

LM309K – LM309 5V 1A Voltage Regulator Datasheet

Making some random assumptions about the side datashwet diodes in a ‘, I get a number like a few million Ohms. It is not necessary to bypass the output, although this does improve transient. Haha, okay, well that explains the weird readings then!

This divides the output to the same voltage as the internal reference. Wiring errors always exceed parts problems.

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. If forward across a diode they read about half-scale on all ranges. 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 published plan for ‘ is not so simple, and I can’t identify your 3K dtasheet a glance.

That was a Clue. With a heat sink, the effective thermal resistance can only approach the values specified, depending on the efficiency of the sink. I’m testing them to make sure I’ve got the correct pinout and they work properly.

In old days we used Needle Meters which worked from a 1. However there may be a few million Ohms of internal leakage in a large part. When you study regulators you will find a couple of resistors out-to-ground. Datasheet pdf – http: The first regs had 14 or 8 pins and may have needed an external transistor such as your 2N to handle big loads.

A voltage regulator is several transistors working together. The devices are available in the TO3 power package. But a toaster, a radio, and a PC are all “boxes with wall-plugs”, yet not the same thing.

The regs you buy may have 40 transistors to improve action and reduce abuse little transistor are incredibly cheap.

Considerable effort was expended to make these devices easy to use and lm30k9 the number of. They could still be a break inside the plastic– a barely-not-rejected batch of plastic might have millions-Ohm leakage between pin stubs. Current limiting is included to limit the peak output current to a safe value. Haha So are these readings what you’d expect to see lm309, these components?

With a heat sink, the effective thermal. The Silicon diode hardly turns-on until you get 0.

The available output current is greater than 1A. Honestly I’m not sure how to tell from the data sheet. I ordered several transistors for each model and they all behave the same way, which leads me to believe they are “right”
