Last update 6 January The formulae to calculate the Output voltage based on the value of resistors is.

So, if you are looking for a variable voltage regulator to set voltage between 1. TL — Programmable Reference Voltage.

TL — Programmable Reference Voltage. 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. This pins adjusts the output voltage.

LMT Voltage Regulator Pinout, Equivalent, Specs & Datasheet

Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator.

You don’t want to use too high an dagasheet voltage as the excess will need to be dissipated as heat through the regulator.

Apart from l3m50t the IC also has current regulator mode which makes it suitable for battery charging applications. The regulated output voltage set by the adjust pin can be obtained from this pin.

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 Datashret. The value of Iadj will be 50uA always since the reference voltage is 1. When external capacitors are used datasneet 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.

Submitted by admin on 21 October Apart from thus the IC also has current regulator mode which makes it suitable for battery charging applications. To determine the output datashest, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.

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 input voltage which has dataseet be regulated is given to this pin.

When it comes to variable voltage regulation requirements, LM would most likely be the first choice. The value of Iadj will be 50uA always since the reference voltage is 1. 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.

Plan to be about 3V about the desired output voltage. Please update your bookmarks. It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator.

But one shortcome of that IC is that it can source only a maximum of 1. Normally, no capacitors are needed unless the device is situated more than mm 6 inches from the input filter capacitors in which case an input bypass capacitor is required.

Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. Submitted by admin on 21 October An optional output capacitor can be added to improve transient response. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.

The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. The dropout voltage of the IC regulator is about 1.

The LM voltage regulators can provide up to 1. This pins adjusts the 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 datasheef divider. However, other values such as or ohms can also be used for R 1. The input voltage which has to be regulated is given to this pin.
