LMK Datasheet(PDF) – STMicroelectronics

No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. 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. Plan to be about 3V about the desired output voltage. Last update 6 January Created 28 July Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator.

Please update your bookmarks. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. However, other values such as or ohms can also be used for R 1. Even small pm338k 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.

datsaheet The dropout voltage of the IC regulator is about 1. 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. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements. 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 the regulator.

Where greater output current is required, the LM series regulators are datashee up to 3A and the LM series voltage regulators for up to 5A of output. 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.

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