Message 1 of 5. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated darasheet these 79XX ICs.

LM NTE Equivalent NTE 5V negative voltage r – Wholesale Electronics

TL — Programmable Reference Voltage. The output regulation is specified for a current change from 5 mA to 1 A.

If anyone has suggestions I would be most gratefull. These capacitors should be placed close to the terminals for them to work effectively.

Voltage Regulator IC | Datasheet

Brief Datasheeg on Voltage Regulator Voltage regulators are very common in electronic circuits. Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page.


This is a typical application circuit of the IC. 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 Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. Message 3 of 5.

LM 7905 CT

The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds. 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 l,7905.

Try putting a load resistor from each output to ground. The output current of this IC can go up to 1. Also they should be of ceramic type, since daatsheet capacitors are faster than electrolytic.

Why do we need Negative Voltage Regulators? Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. Multisim Voltage reg simulation. The maximum value is mV.

Voltage regulators are very common in electronic circuits. Screen capture is attached. The input capacitor 2. They provide a constant output voltage for a varied input voltage. So I lj7905 back to the LM but that still resulted in the incorrect output. Most Active Software Boards: Message 4 of 5.

Submitted by admin on 10 June My mistake must be simple, but I can’t spot it. Although the datasheet does not specify or call for any minimum load, it also does not datasheeh the performance at no load. Message 2 of 5. Message 5 of 5. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you datssheet. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

This 7 Watts will be dissipated as heat.
