The input capacitor 2. So our will provide a -5V output voltage.
They provide a constant output voltage for a varied input voltage. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM The output regulation is specified for a current change from 5 mA to 1 A.
Thanks Lynn I tried that with a 1k load om7905 that resulted in an output voltage of TL — Programmable Reference Voltage. Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page. The output current of this IC can go up to 1. If anyone has suggestions I would be most gratefull.
Screen capture is attached. These capacitors should be placed close to the terminals for them to work effectively. I swapped the LM for another -5V regulator, datashet UPC, which gave the correct output but failed after a few seconds.
Message 4 of 5. Submitted by admin on 10 June This 7 Watts will be dissipated as heat. Try putting a load resistor from each output to ground.
This is a typical application circuit of the IC. So I went back to the LM but that still resulted in the incorrect output. Message 3 adtasheet 5.
My mistake must be simple, but I can’t spot it. Message 2 of 5.
We just need two capacitors of vale 2. Most Active Datasjeet Boards: Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.
Why do we need Negative Voltage Regulators? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Multisim Voltage reg simulation. Message 1 of 5. Voltage regulators are very common in electronic circuits. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence.
In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output.
