It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator. When external capacitors are used with a voltage regulator it may be necessary to use protection diodes to prevent the capacitors from discharging through low current points into the voltage regulator. Last update 6 Lm350f See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.

Submitted by admin on 21 October Once easy way to do this, is to use this online calculator to randomly substitute the value of resistors you have datashwet check which output voltage you will get.

However, other values such as or ohms can also be used for R 1. So, if you are looking for a variable voltage regulator to set voltage between 1. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.

LM / LM / LM Voltage Regulator Calculator and Circuits

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

The input voltage which has to be regulated is given to this pin. Created 28 July Plan to be about 3V about the desired output voltage. 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 dropout voltage of the IC regulator is about 1. The regulated output voltage set by the adjust pin can be obtained from this pin. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

The regulated output voltage set by the adjust pin can be obtained from lm350h pin.

The value of Iadj will be 50uA always since the reference voltage is 1. But one shortcome of that IC is that it can source only a maximum of 1. Datasgeet — Programmable Reference Voltage.

Apart from thus the IC also has current regulator mode which makes it suitable for battery charging applications. The formulae to calculate the Output voltage based on the value of resistors is. As said earlier the IC has three pins, in which the input voltage is supplied to pin3 V IN 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 V OUT. Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output.

You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. When it comes to variable voltage regulation requirements, LM would most likely be the first choice.

This pins adjusts the output voltage. 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 datashheet accordingly.

Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.

It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator. TL — Programmable Reference Voltage. 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. This pins adjusts the output voltage.

An optional output capacitor can be added to improve transient response. So, if you are looking for a variable voltage regulator to set voltage between 1.
