Tell us exactly what you want to do abd we can help you out. Cathode, Anode, and REF. Sep 7, 2, If you want to slap me in the face, I don’t blame you. The transistor is only on when the voltage is between the 2 limits.

If you want 2. Mar 1, 7. Ln431 then I presume the other resistors and capacitors are for BJT biasing? If I understand this correctly, feeding a different voltage into REF will change the VZener and thus you get a different output voltage? Eliminates the use of a lot of resistors and op-amps. You’re contributions are priceless.


Yes, my password is: Sep 2, 2. You May Also Like: But what exactly is going on here?

Please help me understand LM operation!? | All About Circuits

Now about your Voltage Protection circuit The first is similar to the shunt regulator except the output get’s connected into middle of the resistor divider for the second I know you guys aren’t my personal teachers, so I hope I don’t come off that way.

Please help me understand radio electronics! I can’t tell you what is a better shunt regulator but I can tell you that the circuit shown will smoke the transistor. Do you already have an account? If you go over the high limit, the RA string will cause the left to conduct which dumps the voltage on the RB llm431, shuts off the right and the transistor goes off for overvoltage.

I suggest you go to vendor websites and do searches for shunt regulators. There are 3 pins on the LM Well I know I just asked a lot of questions.

Your name or email address: Feb 17, 4, 1, You need a resistance in series with the base in order to keep the right from trying to get the base all the lm4311 up to Vbatt. Page 9 of the datasheet shows the internal diagram of the Feb 29, 3.
