Note: 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. They provide a constant output voltage for a varied input voltage. In our case the IC is an negative 5V regulator, meaning it provides -5V as output. So our will provide a -5V output voltage.
The output current of this IC can go up to 1. This 7 Watts will be dissipated as heat. Negative voltage regulators are mainly used in Op-Amp and other circuits where a negative supply voltage is needed.
In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs.
This is a typical application circuit of the IC. We just need two capacitors of vale 2. The input capacitor 2. These capacitors should be placed close to the terminals for them to work effectively.
Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. Subscribe to stay updated with industry's latest Electronics components and news. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits.
