Datashet 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. Plan to be about 3V about the desired output voltage.

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

National Semiconductor

Solid tantalum capacitors can be used on the voltage output datashee improve the ripple rejection of the voltage regulator. When it comes to variable voltage regulation requirements, LM would most likely be the first choice. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator.

The value of Iadj will be 50uA always since the reference voltage is 1.

Submitted by admin on 21 October Apart from thus the IC also has current dattasheet mode which makes it suitable for battery charging applications. 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.

Plan to be about 3V about the desired output voltage. The formulae to calculate the Output voltage based on the value of resistors is.

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. 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.

Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection.

To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

The LM voltage regulators can provide up to 1. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. The dropout voltage of the IC regulator is about 1. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator.

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 1 Adjust which will decide the output voltage of the IC that is given out at pin 2 V OUT. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection.

Where greater output current is required, the LM series regulators are suitable up to adtasheet and the LM series voltage regulators for up to 5A of output. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.

However, other values such as or ohms can also be used for R 1. To determine the output voltage, enter values for the program R 1 and set R 2 resistors daasheet hit the “Calculate” button.

Created 28 July Last update 6 January Normally, no capacitors are needed unless the device is situated more than mm dxtasheet inches from the input filter capacitors in which case an input bypass capacitor is required. The dropout voltage of the IC regulator is about 1.

Last update 6 January It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator. The LM lk350t regulators can provide up to 1. An optional output capacitor can be added to improve transient response.

An optional output capacitor can be added to improve transient response. 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 lm50t points into the voltage regulator.

So, if you are looking for a variable voltage regulator to set voltage between 1. Even small datasyeet can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. TL — Programmable Reference Voltage. The input voltage which has to be regulated is given to this pin.
