LM317BT DATASHEET PDF

When it comes to variable voltage regulation requirements LM would most likely be the first choice. Apart from using it as a variable voltage regulator, it can also be used as a fixed voltage regulator, current limiter, Battery charger, AC voltage regulator and even as an adjustable current regulator. One notable drawback of this IC is that it has a voltage drop of about 2. So, if you are looking for a variable voltage regulator to deliver current up to 1. LM is a 3-terminal regulator IC and it is very simple to use.

Apart from using it as a variable voltage regulator, it can also be used as a fixed voltage regulator, current limiter, Battery charger, AC voltage regulator and even as an adjustable current regulator. One notable drawback of this IC is that it has a voltage drop of about 2.

So, if you are looking for a variable voltage regulator to deliver current up to 1. LM is a 3-terminal regulator IC and it is very simple to use. It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator.

As said earlier the IC has 3 pins, in which the input voltage is supplied to pin3 VIN then using a pair of resistors potential divider we set a voltage at pin 1 Adjust which will decide the output voltage of the IC that is given out at pin 2 VOUT.

Now to make it act as a variable voltage regulator we have to set variable voltages at pin 1 which can be done by using a potentiometer in the potential divider.

The below circuit is designed to take 12V you can supply up to 24V as input and regulate it from 1. The Resistor R1 1K and the potentiometer 10k together creates a potential difference at adjust pin which regulates the output pin accordingly. The formulae to calculate the Output voltage based on the value of resistors is.

And the simulation shows 7. You can vary the output voltage by simply varying the potentiometer. In our circuit, a motor is connected as a load which consumes around mA you can connect any load up to 1. The same formulae can also be used to calculate the value of resistor for you required output voltage. One easy way to do this is to use this online calculator to randomly substitute the value of resistors you have and check which output voltage you will get.

The is an adjustable 3-terminal positive voltage regulator capable of supplying in excess 1. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow-out proof. The LM serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM can be used as a precision current regulator.
