Making some random assumptions about the side of diodes in a ‘, I get a number like a few million Ohms.

With a heat sink, the effective thermal. Regulators are a specific complete function and the pin names make some sense. Considerable effort was expended to make these devices easy to ,m309k and minimize the number of. The regs you buy may have 40 transistors to improve action and reduce abuse little transistor are incredibly cheap. Transitors darasheet simple incomplete functions and the pins have abstract names.

With a heat sink, the effective thermal resistance can only approach the values specified, depending on the efficiency of the sink. Now measure 5V from Out to Gnd. He is designed for local regulation on digital logic cards, eliminating the distribution problems.

A simple reg would include a voltage reference L3m09ka small transistor to compare that reference to the output voltage, and a big transistor to pass the correct amount of power through.

So here’s my question. Okay, well thanks very much for clarifying that! All you really proved is that the legs are not broken-off.

I’m testing them to make sure I’ve got the correct pinout and they work properly. It is not necessary to bypass the output, although this does improve transient response somewhat. Haha, okay, well that explains the weird readings then! Current limiting is included to limit the peak output current to a safe value.

Current limiting is included to limit the peak output. The devices are available in the TO3 power package. Considerable effort was expended to make these devices easy to use and minimize the number of external components.

Tekay Member Halmstad-Sweden Posts: Thanks so much for your help!!!! He is designed for local regulation on digital logic cards, eliminating the distribution problems associated with single-point regulation.

Haha So are these readings datasheet you’d expect to see from these components? I understand wanting to test. Honestly I’m not sure how to tell from the data sheet. Today we use digital meters which mostly only use 0. They could still be a break inside the plastic– a barely-not-rejected batch of plastic might have millions-Ohm leakage between pin stubs. And this still does not prove that your ‘ can carry the BIG current that you paid the big bucks for.

It is not necessary to bypass the output, although this does improve transient. Wiring errors always exceed parts problems.

Note that the battery has to hold at least 7V into the part, because the minimum In-Out voltage is 1. Input bypassing is needed, however, if the regulator is located very far from the. That was a Clue. Is this right for this transistor???

When you study regulators you will find a couple of resistors out-to-ground. For these transistors, brand new from Jameco, do these ‘s look right?

However you datasehet 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. The Silicon diode hardly turns-on until you get 0. 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.

In fact the conductance at 0. The regulators are essentially blow-out proof. I ordered several transistors for each model and they all behave the same way, which leads me to believe they are “right” In old days we used Needle Meters which worked from a 1. Input bypassing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. This is “too small for real work” but can be detected by many meters. The first regs had 14 or 8 pins and may have needed an external transistor such as your 2N to handle big loads.

While PCs usually don’t have bread-slots, with transistors and regulators you gotta go datsaheet the part number.
