Lm385z Datasheet Marvelous Lm385z 1 2 Datasheet Pdf On Semiconductor
AltAir 2 When the dahasheet is less than 5V they can be neglected. The problem you’re encountering datashedt that R1 is so high that it doesn’t let enough current flowing through to operate the diodes as they should.
Email Required, but never shown. 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 D2 and D3 are not present.
The circuit operates as a resistive voltage divider.
Em Ka 48 7. Andy aka k 10 Sign up using Email and Password. I changed R2 and R3 to 47k and 22k and all works fine! Em Ka, D2 and D3 ‘start working’ when the voltage is higher to 5V in. Post as a guest Name.
Enric Blanco 4, 5 11 I don’t understand what you mean by resistive voltage divider – could you please explain? Home Questions Tags Users Unanswered.

Besides, from what I understand voltage across anode of D1 and cathode of D2 should be always 5V, right? Sign up using Facebook.
You can’t do this with one 9V battery. If you don’t feed them with enough current and voltage they are just resistors. Sign up or log in Sign up using Google. To achieve the desired result descending resistance R1.

However when I measure it, Lm835z is only 2. However, at 4V voltage drop, the 10k resistor can only provide 0. 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.
Then the curtain will rise. Add that to your 5Volts, and you have The diodes need, according to the datasheet, a minimum of 20 uA to operate. You must select a value well below this.
As if datassheet are not. I’m doing a simple circuit using LM This, of course, ignores your bias current through your LM And it is so, if R2 and R3 are not present in the circuit. Could someone explain me please what am I missing? Select a lower value for R1. Just think about it a while and calculate what the voltage at that junction is with D2 and D3 removed.
