Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM We just need two capacitors of vale 2.

Submitted by admin on 10 June This 7 Watts will be dissipated as heat. My mistake must be simple, but I can’t spot it. Screen capture is attached. Why do we need Negative Voltage Regulators?

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.

Most Active Software Boards: Try putting a load resistor from each output to ground. So our will provide a -5V output voltage. Multisim Voltage reg simulation. Message 2 of 5. Depending on the construction of the model km7905 the regulator, it is possible that it needs a minimum load.

The maximum value is mV. Message 4 of 5. The input capacitor datssheet. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output.

Message 5 of 5. Dattasheet 3 of 5. The output current of this IC can go up to 1. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

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

They provide a constant output voltage for a varied input voltage. Negative voltage regulators are mainly used in Op-Amp lmm7905 other circuits where a negative supply voltage is needed.

In many cases dstasheet an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load.

LM Negative Voltage Regulator Pinout, Specs, Circuit & Datasheet

Message 1 of 5. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. The output regulation is specified for a current change from 5 mA to 1 A. 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 I went back to the LM but that still resulted in the incorrect output.

TL — Programmable Reference Voltage. Voltage regulators are very common in electronic circuits. These capacitors should be placed close to the terminals for them to work effectively. This is a typical application circuit of the IC. Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page.
