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 is a voltage regulator datasheef a 5V output, it needs some current to operate. Sparky 11k 2 15 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.

Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

The output current of this IC can go up to 1. Post as a guest Name. They provide a constant output voltage for a varied input voltage.


Spehro Pefhany k 4 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. Email Required, but never shown.

This will stabilize the input and output voltage’s. But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. Why c Voltage regulator drops the current if the current enters around 13mA to 7mA? I understand your voltage divider is to limit U1 Vin to 25 volts.

TL — Programmable Reference Voltage. The maximum GND current is 8. Voltage regulators are very common in electronic circuits.

This 7 Watts will be dissipated as heat. Datashest up using Email and Password. These capacitors should be placed close to the terminals for them to work effectively.

LM Voltage Regulator Datasheet. This is a typical application circuit of the IC. So turn to the datasheet curves, and you’ll find these: In our case the IC is an iconic regulator IC that finds its application in most 77805c the projects.

Submitted by admin on 30 August Here, the input voltage can be anywhere between 9VV, and the output voltage can be adjusted using the value of resistance R1 and R2. This will help the LM maintain a stable output voltage even with changes in load. The value of R17 is not shown because it is different for different regulator output voltages eg.

The value can be calculated using the below formulae. Sign up using Facebook. Sign up or log in Sign up using Google. Have a look at a typical datasheet and see the data related to the “quiescent current”.

The input capacitor 0. 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.

I know there should be voltage and current drop from the voltage regulator but my question is why current drops off? We just need two capacitors of vale 33uf and 0.
