Please update your bookmarks. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. The dropout voltage of the IC regulator is about 1. You don’t want to use too high an datssheet voltage as the excess will need to be dissipated as heat through the regulator.

The LM voltage regulators can provide up to 1. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator.

An optional output capacitor can be added to improve transient response.

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

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

Last update 6 January 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. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.

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. Although the surge is very short in duration, there 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 datasheett the voltage regulator. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator.
