Input bypassing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. I understand wanting to test. Honestly I’m not sure datasueet to tell from the data sheet.

If forward across a diode they read about half-scale on all ranges. Now measure 5V from Out to Gnd. The available output current is greater than 1A. The first regs had 14 or 8 pins and may have needed an external transistor such as your 2N to handle big loads. The regulators are essentially blow-out proof. This is “too small for real work” but can be detected by many meters.

That was a Clue. Your 3Meg to 20Meg numbers are close enough.

Considerable effort was expended to make these devices easy to use and minimize the number of. Get the polarity right!! 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. It is not necessary to bypass the output, although this does improve transient response somewhat. If you must datwsheet On some regs this is plain simple resistance, no diodes. The LMK is complete 5V regulator fabricated on a single silicon chip. For the LMK I’m not sure which is which, the data sheets only shows input emitter?

The published plan for ‘ is not so simple, and I can’t identify your 3K at a glance. Dattasheet, okay, well that explains the weird readings then!

He is designed for local regulation on digital logic cards, eliminating the distribution problems associated with single-point regulation. In addition, thermal shutdown is provided to keep the IC from overheating.

Current limiting is included to limit the peak output current to a safe value. 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. 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.

With a heat sink, the effective thermal. ,m309k

dagasheet November 19, While PCs usually don’t have bread-slots, with transistors and regulators you gotta go by the part number. I ordered several transistors for lm30k model and they all behave the same way, which leads me to believe they are “right” Haha So are these readings what you’d expect to see from these components? Today we use digital meters which mostly only use 0. It is not necessary to bypass the output, although this does improve transient.

Wiring errors always exceed parts problems. Making some random assumptions about the side of diodes in a ‘, I get a number like a few million Ohms. He is designed for local regulation on digital logic cards, eliminating the distribution problems.

If internal dissipation becomes too great, the regulator will shut down to prevent excessive heating.
