Message 4 of 5. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. Multisim Voltage reg simulation. This 7 Watts will be dissipated as heat. My mistake must be simple, but I can’t spot it.

LM Datasheet PDF –

Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed. Auto-suggest adtasheet you quickly narrow down your search results by suggesting possible matches as you type.

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. Message 5 of 5. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of TL — Programmable Reference Voltage. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output.

Message 1 of 5. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

In our case the IC is an negative 5V regulator, meaning it provides -5V as output. Depending daatsheet the construction of the model for the regulator, it is possible that it needs a minimum load.

These capacitors should be placed close to the terminals for them to work effectively.

Message 3 of 5. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits.

In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. The output current of this IC can go up to 1. Submitted by admin on 10 June Screen capture is attached.

The output regulation is specified for a current change from 5 mA to 1 A. Voltage regulators are very common in electronic circuits.

The maximum value is mV.

So our will provide a -5V output voltage. The input capacitor 2. Most Active Software Boards: So Multisim cannot simulate the output datwsheet a garden variety, ultra common, component like the LM Try putting a load resistor from each output to datasheeet.

This is a typical application circuit of the IC. 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.

If anyone has suggestions I would be most gratefull. Message 2 of 5.

They provide a constant output voltage for a varied input voltage. Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. So I went back to the LM but that still resulted in the incorrect output.
