This 7 Watts will be dissipated as heat. Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. The output regulation is specified for a current change from 5 mA to 1 A.

TL — Programmable Reference Voltage. The maximum value is mV. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

The input capacitor 2. So Multisim cannot simulate the output of a catasheet variety, ultra common, component like the LM Message 4 of 5.

  IEC 60384-1 PDF

Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. Message 1 of 5. This is a typical application circuit of the IC. Message 3 of 5. So our will provide a -5V output voltage. Message 2 of 5.

Try putting a load resistor from each output to ground. We just need two capacitors of vale 2.

Multisim Voltage reg simulation. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. If anyone has suggestions I would dqtasheet most gratefull.

The output current adtasheet this IC can go up to 1. Message 5 of 5. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits.

So I went back to the LM but that still resulted in the incorrect output.

Submitted by admin on 10 June Why do we need Negative L7905 Regulators? Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page.


Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. Most Active Software Boards: They provide a constant output voltage for a varied dagasheet voltage. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. Screen capture is attached.

My mistake must be simple, but I can’t spot it. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.

These capacitors should be placed close to the terminals for them to work effectively. Depending on the construction ratasheet the model for the regulator, it is possible that it needs a minimum load.

I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds. Voltage regulators are very common in electronic circuits.
