So our will provide a -5V output voltage.

My mistake must be simple, but I can’t spot it. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM 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. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. This is a typical application circuit of the IC.

Screen capture is attached. The input capacitor 2. These capacitors should be placed close to the terminals for them to work effectively. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

They provide a constant output voltage for a varied input voltage. Submitted by admin on 10 June Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. We just need two capacitors of vale 2. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs.

This 7 Watts will be dissipated as heat. Message 1 of 5. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page. Why do we need Negative Voltage Regulators? I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds.

View lm7905 datasheet:

Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. The maximum value is mV. Most Active Software Boards: Message 3 of 5.

If anyone has suggestions I would be most gratefull. So I went back to the LM but that still resulted in the incorrect ddatasheet.

The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. TL — Programmable Reference Voltage. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed. Multisim Voltage reg simulation. Message 2 of 5.

The output current of this IC can go up to 1. Message datadheet of 5. Voltage regulators are very common in electronic circuits. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Try putting a load resistor from each output to ground. Message 5 of 5.
