TL — Programmable Reference Voltage. Also they should be of ceramic type, since ceramic daatasheet are faster than electrolytic.
In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

Screen capture is attached. In many cases where an Op-Amp is working in lm79005 mode power supply a negative voltage will be regulated by these 79XX ICs.
The output regulation is specified for a current change from datwsheet mA to 1 A. My mistake must be simple, but I can’t spot it. Multisim Voltage reg simulation.

So our will provide a -5V output voltage. Submitted by admin on 10 June The maximum value is mV. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.
The input capacitor 2. Voltage regulators are very common in electronic circuits. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Message 3 of 5. Try putting a load resistor from each output to ground.
These capacitors should be placed close to the terminals for datasueet to work effectively. Depending on the construction of the model for the regulator, it is possible that it needs a minimum load.
They provide a constant output voltage for a varied input voltage. Why do we need Negative Voltage Regulators? This is a typical application circuit of the IC. This 7 Watts will be dissipated as heat.
We just need two capacitors of vale 2.

Message 5 of 5. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
So I went back to the LM but that still resulted in the incorrect output. Message 1 of 5. Message 2 of 5. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output.

Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. If anyone has suggestions I would be most gratefull.
Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence.
The output current of this IC can go up to 1. Most Active Software Boards: I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load.
Message 4 of 5.
