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.

Spehro Pefhany k 4 The maximum GND current is 8. I know there should be voltage and current drop from the voltage regulator but my question is why current drops off?

In our case the IC is an iconic regulator IC that finds its application in most of the projects. To help even more replace R1 with 2 each 12 volt 5W zener diodes in series to lock the voltage at datashwet VDC at pin 1 of U1. Post as a guest Name.

Home Questions Tags Users Unanswered. Here, the input voltage can be anywhere between 9VV, and the output voltage can be adjusted using the value of resistance R1 and R2. Voltage regulators are very common in electronic circuits. Sparky 11k 2 15 Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

These capacitors should be placed close to the terminals for them to work effectively.

This is a typical application circuit of the IC. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

This Datashdet 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. We just need two capacitors of vale 33uf and 0. But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. This will help the LM maintain a stable output voltage even with changes in load.

Email Required, but never shown. I understand your voltage divider is to limit U1 Vin to 25 volts. Complete Technical Details can be found at the datasheet give at the end of this page.

Have a look at a typical datasheet and see the data related to the “quiescent current”. Sign up or log in Sign up using Google. TL — Programmable Reference Voltage. They provide a constant output voltage for a varied input voltage.

Sign up using Email and Password. That is the current that flows from the input out of the GND pin the input current is the sum of the output current and the GND current. Why c Voltage regulator drops the current if the current enters around 13mA to 7mA? The output current of this IC can go up to 1.

The value of R17 is not shown because it is different for different regulator output voltages 77805c. The is a voltage regulator providing a 5V output, it needs some current to operate.
