The datasheet specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input. The LM78XX series of three terminal regulators is available with several fixed output voltages making them useful in a wide range of applications One of these is.

The maximum GND current is 8. Sparky 11k 2 15 In our case the IC is an iconic regulator IC that finds its application in most of the projects. Why c Voltage regulator drops the current if the current enters around 13mA to 7mA? Complete Technical Details can be found at the datasheet give at the end of this page.

TL — Programmable Reference Voltage. The value can be calculated using the below formulae.
That is the current that flows from the input out of the GND pin the input current is 7805 sum of the output current and the GND current. Sign up using Facebook. Home Questions Tags Users Unanswered.

So turn to the datasheet curves, and you’ll find these: Spehro Pefhany k 4 We just need two capacitors of vale 33uf and 0. To help even more replace R1 with 2 each 12 volt 5W zener diodes in series to lock the voltage at datashet VDC at pin 1 of U1.

Here, the input voltage can be anywhere between 9VV, and the output voltage can be adjusted using the value of resistance R1 and R2. But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current.
I know there should be voltage and current drop from the voltage datashret but my question is why current drops off? The is a voltage regulator providing a 5V output, satasheet needs some current to operate. Voltage regulators are very common in electronic circuits. Have a look at a typical datasheet and see the data related to the “quiescent current”.
Submitted by admin on 30 August They provide a constant output voltage daatasheet a varied input voltage. This IC can also act as an adjustable output voltage regulator, meaning you can also control the output voltage for your desired value using the below circuit. The output current of this IC can go up to 1.
This will help the LM maintain a stable output voltage even with changes in load. This 7 Watts will be dissipated as heat. The input capacitor 0.

This is a typical application circuit of the IC. Post as a guest Name. I understand your voltage divider is to limit U1 Vin to 25 volts.
