The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. Message 4 of 5. The output current datasheeg this IC can go up to 1.

Submitted by admin on 10 June datashset Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. Message 1 of 5.

The output regulation is specified for a current change from 5 ddatasheet to 1 A. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs.

If anyone has suggestions I would be most gratefull. I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds. Message 2 of 5. My mistake must be simple, but I can’t spot it. Most Active Software Boards: We just need two capacitors of vale 2. Screen capture is attached. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

Why do we need Negative Voltage Regulators? Voltage regulators are very common in electronic circuits. Datsaheet on the construction of the model for the regulator, it is possible that it needs a minimum load. So I went back to the LM but that still resulted in the incorrect output.

Message 3 of 5. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed. 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.

Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of So our will provide a -5V output voltage. Try putting a load resistor from each output to ground. Message 5 of 5.

This is a typical application circuit of the IC. This 7 Watts will be dissipated as heat.

The input capacitor 2. Multisim Voltage reg simulation. They provide a constant output voltage for a varied input voltage. Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page.

These capacitors should be placed close to the terminals for them to work effectively. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. TL — Programmable Reference Voltage. The maximum value is mV.
