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

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 Lm33k8 voltage regulators can provide up to 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.

Please update your bookmarks. Created 28 July 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. See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements. An optional output capacitor can be added to improve transient response. Even small capacitors can have a datasneet enough internal series resistance to be able to deliver 20A spikes when shorted.

When external capacitors are used with a voltage regulator lm338, may be necessary to use protection diodes to prevent the capacitors from discharging through low current lm33k into the voltage regulator. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. 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. The LM voltage regulators can provide up to 1.

Last update 6 January Where greater output current is required, the Lm38k series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output. 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. Plan to datashest about 3V about the desired output voltage. 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 dropout voltage of the IC regulator is about 1.

However, other values such as or ohms can also be used for R 1. Llm338k tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. Plan to be about 3V about the desired output voltage. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.
