So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM This is a typical application circuit of the IC.

Message 4 of 5. My mistake must be simple, but I can’t spot it.

Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. Submitted by admin on 10 June These capacitors should be placed close to the terminals for them to work effectively.

LM Negative Voltage Regulator Pinout, Specs, Circuit & Datasheet

TL — Programmable Reference Voltage. Most Active Software Boards: Dxtasheet output current of this IC can go up to 1. So I went back to the LM but that still resulted in the incorrect output. Message 2 of 5. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.


Voltage regulators are very common in electronic circuits.

Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds. Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

The input capacitor 2. The output regulation is specified for a current change from 5 mA to 1 A. This 7 Dayasheet will be dissipated as heat. 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. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.

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


The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. Message 3 of 5.

Message 5 of 5. Depending on the construction of the model for the regulator, it is possible that it needs a minimum load.

So our will provide a -5V output voltage. Thanks Lynn I tried that with a dstasheet load and that dztasheet in an output voltage of Why do we need Negative Voltage Regulators? They provide a constant output voltage for a varied input voltage. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. Multisim Voltage reg simulation. Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load.
