Submitted by admin on 10 June Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output.
Message 5 of 5. Message 2 of 5. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. Message 4 of 5. This 7 Watts will be dissipated as heat. The output regulation is specified for a current change from 5 mA to 1 A. The maximum value is mV. They provide a constant output voltage for a varied input voltage.
The output current of this IC can go up to 1. Why do we need Negative Voltage Regulators? Message 1 of 5. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

If anyone has suggestions I would be most gratefull. So our will provide a -5V output voltage. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Try putting a load resistor from each output to ground. We just need dataaheet capacitors of vale 2. This is a typical application circuit of the IC.

These capacitors should be placed dayasheet to the terminals for them to work effectively. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs.
TL — Programmable Reference Voltage. My mistake must be simple, but I can’t spot it.
Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. In our case the IC is an negative 5V regulator, meaning it provides -5V as output. Although the datasheet does not specify or call for any minimum lm795, it also does not specify the performance at no load. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage lm905 needed. Voltage regulators are very common in electronic circuits.

Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. So I went back to the LM but that still resulted in the incorrect output. Screen capture is attached. I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds.
The input capacitor 2.
