LM / LM / LM Voltage Regulator Calculator and Circuits

To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator.

Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. The LM voltage regulators can provide up to 1.

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

The LM voltage regulators can provide up to 1. See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.

No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. Created 28 July Created 28 July The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. Please update your bookmarks.

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. 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 dxtasheet capacitor is required. See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.

The dropout voltage of the IC regulator is about 1. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. Last update 6 January Solid tantalum capacitors can be used on the voltage output to improve datsaheet ripple rejection of the 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 response.

To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button. No dataseet diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.

The adjustment terminal of dataasheet regulator can be bypassed to achieve very high ripple rejection. However, other values such as or ohms can also be used for R 1.

Last update 6 January 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.

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.

Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. Plan to be about 3V about the desired output voltage. However, other values such as or ohms can also be used for R 1.
