Message 5 of 5. TL — Programmable Reference Voltage. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. This 7 Watts will be dissipated as heat. In our case the IC is an negative 5V regulator, meaning it provides -5V as output. These capacitors should be placed close to the terminals for them to work effectively.

Submitted by admin on 10 June Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Message 3 of 5. The output current of this IC can go up to 1.

Message 1 of 5. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the datasgeet. Voltage regulators are very common in electronic circuits.

The maximum value is mV. My mistake must be simple, but I can’t spot it. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Multisim Voltage reg simulation.

View lm7905 datasheet:

Complete Technical Details can be found datasjeet the LM voltage regulator datasheet given at the end of this page. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits.

The output regulation is specified for a current change from 5 mA to 1 A.

Screen capture is attached. So our will provide a -5V output voltage. Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. If anyone has suggestions I would be most gratefull.

Message 2 of 5. Most Active Software Boards: Negative voltage regulators are mainly used in Op-Amp and other circuits where datashdet negative supply voltage is needed.

In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by dstasheet 79XX ICs. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

We just need two capacitors of vale 2. So I went back to the LM but that still resulted in the incorrect output.

Why do we need Negative Voltage Regulators? Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. They provide dataaheet constant output voltage for a varied input voltage. This is a typical application circuit of the IC.

Message 4 of 5. The input capacitor 2.

Try putting a load resistor from each output to ground. I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds.
