LM Datasheet(PDF) – National Semiconductor (TI)

Message 1 of 5. Depending datashee the construction of the model for the regulator, it is possible that it needs a minimum load. The maximum value is mV.

They provide a constant datashset voltage for a varied input voltage. The output regulation is specified for a current change from 5 mA to 1 A. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of So our will provide a -5V output voltage.

Message 2 of 5. Complete Technical Details can be found at the LM voltage l,7905 datasheet given at the end of this page. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Message 3 of 5. So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM Most Active Software Boards: Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.

Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits.

We just need two capacitors of vale 2. These capacitors should be placed close to the terminals for them to work effectively.

LM Negative Voltage Regulator Pinout, Specs, Circuit & Datasheet

So I went back to the LM but that still resulted in the incorrect output. Message 5 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. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a llm7905 and correct output. TL — Programmable Reference Voltage. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

If anyone has suggestions I would be most gratefull.

Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. I swapped the LM for another -5V regulator, the UPC, which gave the correct output datashedt failed after a few seconds. The output current of this IC can go up to 1.

Try putting a load resistor from each output to ground.

My mistake must be simple, but I can’t spot it. Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence. Screen capture is attached.

The input capacitor 2. Submitted by admin on 10 June Multisim Voltage reg simulation. Why do we need Negative Voltage Regulators?
