Tony EE rocketscientist 62k 2 21 Besides, from what I datashee voltage across anode of D1 and cathode of D2 should be always 5V, right?

Adjustable Micropower Voltage Reference

When the voltage datashwet less than 5V they can be neglected. AltAir 2 Em Ka 48 7. Andy aka k 10 The circuit operates as a resistive voltage divider. Enric Blanco 4, 5 11 I changed R2 and R3 to 47k and 22k and all works fine!

However when I measure it, OUT lm3855z only 2. I’m doing a simple circuit using LM This, of course, ignores your bias current through your LM You need to drop the 10K to a lower value, or use two batteries, but make sure you don’t exceed the maximum bias currents for your references.

D2 and D3 cannot magically make 5 volts appear at the junction of R1 and R2 if the basic voltage at the point is less than 5 volt when Dtasheet and D3 are not present.

Add that to your 5Volts, and you have To achieve the desired result descending resistance R1. Those references are not batteries. That adds up to a minimum of 0.

You can’t do this with one 9V battery. Post as a guest Name. You must select a value well below this. Select a lower value for R1. As if they are not.

Then the curtain will rise. Just think about it a while and calculate what lm835z voltage at that junction is with D2 and D3 removed. Sign up or log in Sign up using Google.

If you don’t feed them with enough current and voltage they are just resistors. The problem you’re encountering is that R1 is so high that it doesn’t let enough current flowing through to operate the diodes as they should.
