See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements. Although the surge is very short in duration, datsaheet is enough energy to damage parts of the regulator IC. 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. The dropout voltage of the IC regulator is about 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.

Last update 6 January Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. 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 adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. Plan to be about 3V about the desired output voltage. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. 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.

Last update 6 January An optional output capacitor can be added to improve transient response. Solid tantalum capacitors can be datasheer on the voltage output to improve the ripple rejection of the voltage regulator.

To determine the output voltage, 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. 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. 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. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.
