Created 28 July To determine the output voltage, enter values datasneet the program R 1 and set R 2 resistors and hit the “Calculate” button. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC.

To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button. 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.

See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.

You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. Please update your bookmarks. 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 dropout voltage of the IC regulator is about 1.

See the voltage dagasheet datasheets above for specific details regarding the dropout voltage and heatsink requirements. The dropout voltage of the IC regulator is about 1. An optional output capacitor can be added to improve transient response. Last update 6 January An optional output capacitor can be added to improve transient response.

Created 28 July Solid 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.

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. However, other values such as or ohms can also be used for R 1.

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

Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC.

No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. When external capacitors are used with a voltage regulator it may be necessary to l,338k 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.

The LM voltage regulators can provide up to 1. However, other values such as lm3388k ohms can also be used for R 1. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.
