The formulae to calculate dattasheet Output voltage based on the value of resistors is. It has many application circuits in its datasheet, but this IC is known for being used as a variable voltage regulator.
Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC.
An optional output capacitor can be added to improve transient datashee. 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.
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.
Last update 6 January An optional output capacitor can be added to improve transient response. See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.
The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. However, other values such as or datasueet can also be used for R 1. 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.
LM / LM / LM Voltage Regulator Calculator and Circuits
Submitted by admin on 21 October Normally, no capacitors are needed unless the device is datashert more than mm 6 inches from the input filter capacitors in which datasheet an input bypass capacitor is required.
You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button. The value of Iadj will be 50uA always since the reference voltage is 1.

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. To determine the output datashedt, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.
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. Please update your bookmarks. TL — Programmable Reference Voltage. The LM voltage regulators can provide up to 1. When it comes to variable voltage regulation requirements, LM would most likely be the first choice.
Please update your lm530t. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. 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. But one shortcome of that IC is that it can source only a maximum of 1. The regulated output voltage set by the adjust pin can be obtained from this pin. Once easy way to do this, is to use this online calculator xatasheet randomly substitute the value of resistors you have and check which output voltage you will get.
No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. This pins adjusts the output voltage. Created 28 July So, if you are looking for a variable voltage regulator to set voltage between 1. 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.
Datwsheet 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.
