TL — Programmable Reference Voltage. The LM voltage regulators can provide up to 1. This pins adjusts the output voltage.
The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. Created 28 July Datasheer formulae to calculate the Output voltage based on the value of resistors is. But one shortcome of that IC is that it can source only a maximum of 1. The formulae to calculate the Output voltage based on the value of resistors is.
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 value of Iadj will be 50uA always since the reference voltage is 1. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the datqsheet regulator.
However, other values such as lm35t0 ohms can also be used for R 1.

Submitted by admin on 21 October You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. 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.
The regulated output voltage set by the adjust pin datassheet be obtained from this pin. It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator.
See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements. TL — Programmable Reference Voltage.
LM317 / LM338 / LM350 Voltage Regulator Calculator
Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. 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. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.
Last update 6 January But one shortcome of that IC is that it can source only datashet maximum of 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.
It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator. Datadheet, if you are looking for a variable voltage regulator to set voltage between 1. The regulated output voltage set by the adjust pin can be obtained from this pin.

The input voltage which has to be regulated is given to this pin. 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. Apart from thus the IC also has current regulator mode which makes it suitable for datashete charging applications. The input voltage which has to be regulated is given to this pin. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC.
The value of Iadj will be 50uA always since the reference voltage is 1. Plan to be about 3V about the desired output voltage. When it comes to variable voltage regulation requirements, LM would most likely be the first choice. Submitted by admin on 21 October 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.
