DATASHEET LM350 PDF

Adjustable pin adjusts the output voltage and gives the fixed voltage when grounded. Features Delivers an output current of 3 Amps. Output voltage is adjustable from 1. Provides a load regulation of 0. The chip can bear maximum input to an output voltage difference of 35V. For normal operation, it should be 15 volts.

This pins adjusts the output voltage 2 The regulated output voltage set by the adjust pin can be obtained from this pin 3 The input voltage which has to be regulated is given to this pin Adjustable 3-terminal positive voltage regulator Output voltage can be set to range from 1. But one shortcome of that IC is that it can source only a maximum of 1.

So, if you are looking for a variable voltage regulator to set voltage between 1. Apart from thus the IC also has current regulator mode which makes it suitable for battery charging applications. 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 three 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 Resistor R1 should be R and the potentiometer can be upto 10k together creates a potential difference at adjust pin which regulates the output pin accordingly. The value of Iadj will be 50uA always since the reference voltage is 1.

Once 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. Used for Positive voltage regulations Variable power supply.

LM350 Adjustable Output, Positive Voltage Regulator

ACV will flow F1 for protection when the overload or too much voltage input. Next, they will through CuF electrolytic capacitor smooth filter the pulsating voltage from a transformer into a steady direct current DC. Which it is an adjustable regulator IC that designed to many supplies for 3 Amp output and adjustable over 1. LM datasheet How to use LM?
