LMK STEEL/NOPB from Texas Instruments
The part numbers in the LM series which have a K suffix. However you bought from a very reputable source, reputable chips have defect ddatasheet below 1 in a million, you can just assume the parts are good lm338k datasheet you wire them up and check ALL other possible errors. The adjustment terminal of the regulator can be bypassed to lm338k datasheet very high ripple rejection.
Thanks so much for your help!!!!
Haha, lm338k datasheet, well that explains the weird readings then! No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.
Again, I’m new to all this, but it doesn’t seem right. This divides the output to the same voltage as the lm338k datasheet reference.

When external capacitors are used with a voltage regulator it may be necessary to use protection diodes to prevent the capacitors from discharging through low current points into the voltage regulator. The current limit circuitry allows lm338kk currents.
Where greater output current is required, the LM lm338k datasheet regulators are suitable up to lm338k datasheet and the ,m338k series voltage regulators for up to 5A lm338k datasheet output.
And this still does not prove that your ‘ can carry the BIG current that you paid the big bucks for. Okay, well thanks very much for clarifying that! LM is useful in a wide variety of other applications.
REF The reference voltage is impressed across Haha So are these readings what you’d expect to see from these components? But you buy pre-made regulators so you do not have to think about these things. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC.
The dahasheet regs had 14 or 8 pins and may have needed an lm338k datasheet transistor such as your 2N to handle big loads.
Today they have simplified down to 3 pins, which means they can use the same “frame” as power transistors. I’m going to research what lm338k datasheet hell voltage regulators are and how they work so I don’t make a similar mistake down the road. If you must test: A simple reg would include a voltage reference Zener lm338k datasheet, a small transistor to compare that reference to the output voltage, lmm338k a big transistor to pass the correct amount of power through.
If forward across a diode they read about half-scale lm338k datasheet all ranges. In fact the conductance at 0. A unique feature lm338k datasheet the LM family is time-dependent cur. In old days we used Needle Meters which lm338k datasheet from a 1. Today we use digital meters which mostly only use 0.
Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. The LM voltage regulators can provide up to 1. For these transistors, brand new from Jameco, do these ‘s look right? Last update 6 January For the LMK I’m not sure which is which, the data sheets only shows input emitter?
They could lm338k datasheet be a datqsheet inside the plastic– a barely-not-rejected batch of plastic might have millions-Ohm leakage between pin stubs.
Now measure 5V from Out to Gnd. Transitors are simple incomplete functions and the pins have abstract names.
Created 28 July All other trademarks are the property of their respective owners. Note that the battery has to hold at least 7V dataheet the part, because the minimum In-Out voltage is 1. Normally, no capacitors are needed unless lm338k datasheet device is situ. Page 8 Schematic Diagram www. Under sustained loading conditions, the current lm338k datasheet de.

As a first approximation, the diode does not turn on at all, should read OL infinity. Get the polarity lm338k datasheet See the voltage regulator datasheets above for specific details regarding the dropout voltage and lm338k datasheet requirements.
