Message 5 of 5. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. The maximum value is mV. The input capacitor 2.

Message 3 of 5. The output regulation is specified for a current change from 5 mA to 1 A. In our case the IC is an negative 5V regulator, meaning it provides -5V as output. My mistake must be simple, but I can’t spot it. Most Active Software Boards: This 7 Watts will be dissipated as heat.

Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. So our will provide a -5V output voltage.


Message 1 of 5. Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load.

Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. We just need two capacitors of vale 2. 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. Voltage regulators are very common in electronic circuits. If anyone has suggestions I would be most gratefull. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Message 4 of 5. They provide a constant output voltage for a varied input voltage. This is a typical application circuit of the IC. So I went back to the LM but that still resulted in the incorrect output.

Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. TL — Programmable Reference Voltage. Screen capture is attached. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. Submitted by admin on 10 June Try putting a load resistor from each output to ground. So Multisim cannot simulate the output of daatsheet garden variety, ultra common, component like the LM Message 2 of 5.


Multisim and Ultiboard

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.

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

Multisim Voltage reg simulation. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of
