Indeed it would seem to be a much easier solution to just get an adjustable LDO, if this thing is meant to be used as regulated supply voltage. If you want to get 3. Zeners are notoriously power inefficient even at no load. As shown in the circuit below which models the behavior that you are seeing of a voltage reading of about 4V from the zener diode simulate this circuit — Schematic created using CircuitLab.

If you want decent accuracy throw the zeners away and use some low dropout 3. For all private orders, please choose from among those companies only. At least at no load or very small load the LDO regulator will be way more efficient.

Please give us your feedback about this page Click Here. The problem is how you are modeling your circuit, because the series resistance you are using is so close the zener resistance, it must included in the circuit model.

I suppose the point is, at 70mA, according to the datasheet, the voltage across the zener should be 3. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units 2. I see your edited?

Kvegaoro 2, 11 In fact, as I increase and decrease the resistor value, the Zener voltage datasheeh and decreases along with it. Other Product from Integrated Circuits. Actually, it was a candidate for a regulated supply fed by a CCS. Null 4, 10 22 Rather than use rules of thumb which you may or may not understand, you should first look at the data sheet of the part you’re using. For use in stabilizing and clipping circuits with high power rating.

Home Questions Tags Users Unanswered. As shown in the circuit below which models the behavior that you are seeing of a voltage reading of about 4V from the zener diode. Reference Currency HKD The dynamic resistance describes the small-signal behavior near the test current. What output volta de you require? Is that the dynamic resistance of the zener? You may be on right but it sure makes working out the correct resistor value a chore. The closer to the minimum input voltage the more difficult it will be to avoid large changes in current flowing through the TL It seems odd then that the datasheets would specify an Izt of 69mA if it didn’t show the zener in the best light.

Help improve your experience on DHgate. It’s incorrect to add a voltage at the test current because of the dynamic resistance.

In my experience, low-voltage zeners anything below 5V all seem to have a very soft ‘knee’ and not particularly ‘vertical’ current-vs-voltage curve.

If you include the dynamic resistance in the model, you must dataxheet a lower voltage for the ideal zener. How much current will th load require? Working out the current limiting resistor we have: You don’t say what you saw there.

The ones with voltage of 5. For low voltage shunt regulation either use a series regulator LDO or a device such as the TL which has a band gap reference, and an opamp in a 3-poin package to create an almost perfect “Zener diode”. Does this conflict with what Kvegaoro is saying?

As I pointed out in my query, I used the test currents from the relevant datasheets as a guide. Even if it specified at 70mA, there is going to be some there and in this case it is not negligible therefore it must be incorporated in to your circuit model, that why your circuit analysis provides a different answer but adding the zener resistance to the model gives a solution that approaches more closely your result.
