Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. Message 2 of 5. They provide a constant output voltage for a varied input voltage. Voltage regulators are very common in electronic circuits. The maximum value is mV.

Submitted by admin on 10 June Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits.


Why do we need Negative Voltage Regulators? The input capacitor 2.

Message 1 of 5. So Multisim cannot simulate lm705 output of a garden variety, ultra common, component like the LM If anyone has suggestions I would be most gratefull.

These capacitors should be placed close to the terminals for them to work effectively. Lm79905 Technical Details can be found at the LM voltage regulator datasheet given at the end of this page.

Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. I swapped the LM for daasheet -5V regulator, the UPC, which gave the correct output but failed after a few seconds. Message 5 of 5. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.

Datasheet «LM7905»

Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of TL — Programmable Reference Voltage.

My mistake must be simple, but I can’t spot it. Multisim Voltage reg simulation. Message 4 of 5. Try putting a load resistor from each output to ground.


This is a typical application circuit of the IC. The convergence assistant suggest to switch the integration to the Gear algorithm, which dwtasheet in a stable and correct output.

Screen capture is attached. So I went back to the LM but that still resulted in the incorrect output. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Most Active Software Boards: The output current of this IC can go up to 1.

Message 3 of 5. This 7 Watts will be dissipated as heat. We just need two capacitors of vale 2.

In our case the IC is an negative 5V regulator, meaning it provides -5V as output. The output regulation is specified for a current change from 5 mA to 1 A.

So our will provide a -5V output voltage.
