If anyone has suggestions I would be most gratefull. This 7 Watts will be dissipated as heat. TL — Programmable Reference Voltage.

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.

Most Active Software Boards: These capacitors should be placed close to the terminals for them to work effectively. Voltage regulators are very common in electronic circuits. Message 1 of 5.


The output regulation is specified for a current change from 5 mA to 1 A. Why do we need Negative Voltage Regulators?

So our will provide a -5V output voltage. The output current of this IC can go up to 1. Message 3 of 5.

Message 2 of 5. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. In our case the IC is an negative 5V regulator, meaning it provides -5V as output. Perhaps changes to other options in the “Custom Analysis Darasheet dialog will improve the convergence.

The maximum value is mV. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. So Multisim cannot simulate datashete 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.


The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. Submitted by admin on 10 June We just need two capacitors of vale 2. Message 4 of 5.

Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. This is a typical application circuit of the IC. So I went back to the LM but that still resulted in the incorrect output. Message 5 of 5.

Try putting a load resistor from each output to ground. Multisim Voltage reg simulation. My mistake must be simple, but I can’t spot it. Screen capture is attached. The input capacitor 2.
