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.

This 7 Watts will be dissipated as heat. The input capacitor 0. TL — Programmable Reference Voltage.

Here, the input voltage can be anywhere between 9VV, and the output voltage can be adjusted using the value of resistance R1 and R2. Sign up or log in Sign up using Google. This is a typical application circuit of the IC.

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

LM Voltage Regulator Datasheet. Voltage regulators are very common in electronic circuits. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic. I understand your voltage divider is to limit U1 Vin to 25 volts.

C Datasheet PDF –

The value can be datasgeet using the below formulae. 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. This will help the LM maintain a stable output voltage even with changes in load.


But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current.

Spehro Pefhany k 4 Home Questions Tags Users Unanswered. So turn to the datasheet curves, and you’ll find these: We just need two capacitors of vale 33uf and 0. Why c Voltage regulator drops the current if the current enters around 13mA to 7mA?

Sparky 11k 2 15 This IC can also act datasheef 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.

In our case the IC is an iconic regulator IC that finds its application in most of the projects. Submitted by admin on 30 August 7805cc a look at a typical datasheet and see the data related to the “quiescent current”.


To help even more replace R1 with 2 each 12 volt 5W zener diodes in series to lock the voltage at 24 VDC at pin 1 of U1.

The is a voltage regulator datasyeet a 5V output, it needs some current to operate. Complete Technical Details can be found at the datasheet give at the end of this page.

Post as a guest Name. They provide a constant output voltage for a varied input voltage. This will stabilize the input and output voltage’s. The value of R17 is not shown because it is different for different regulator output voltages eg. 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? Email Required, but never shown. Sign up using Facebook.
