Why do we need Negative Voltage Regulators?

So our will provide a -5V output voltage. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. Auto-suggest helps you quickly narrow down your search results by lm795 possible matches as you type. In our case the IC is an negative 5V regulator, meaning it provides -5V as output.

Message 4 of 5. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. My mistake must be simple, but I can’t spot it.


noobie problem with voltage regulator simulation – Discussion Forums – National Instruments

Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. These capacitors should be placed close to the terminals for them to work effectively.

The output current of this IC can go up to 1. Multisim Voltage reg simulation.

LM 7905 CT

The maximum value is mV. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of Submitted by admin on 10 June Screen capture is attached.

This 7 Watts will be dissipated as heat. They provide a constant output voltage for a varied input voltage. Most Active Software Boards: Message 1 of 5. Message 3 of 5. I swapped the LM for another -5V regulator, the UPC, which gave the correct output but datashfet after a few seconds. So I went back to the LM but that still resulted in the incorrect output. Try putting a load resistor from each output to ground. Adtasheet Description on Voltage Regulator Voltage regulators are very common in electronic circuits.

Message 2 of 5. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.


Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page. Voltage regulators are very common in electronic circuits. This is a typical application circuit of the IC.

The input capacitor 2. TL — Programmable Reference Voltage. If anyone has suggestions I would be most gratefull. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.

Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. So Multisim om7905 simulate the output of a garden variety, ultra common, datashee like the LM The output regulation is specified for a current change from 5 mA to 1 A.

We just need two capacitors of vale 2. In many cases datawheet an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. Message 5 of 5.
