The minimum input voltage required for the LM317KCS to operate is 3V above the output voltage. For example, if the output voltage is 5V, the minimum input voltage would be 8V.
To ensure stability and prevent oscillations, a minimum output capacitance of 1uF is recommended. Additionally, the input capacitor should be at least 10uF to prevent oscillations.
The maximum current that the LM317KCS can deliver is 1.5A. However, it's recommended to derate the current to 1A or less for reliable operation.
The output voltage of the LM317KCS can be adjusted by using a resistive divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the reference voltage (1.25V).
The thermal shutdown temperature of the LM317KCS is typically around 150°C to 170°C. The device will shut down when the junction temperature exceeds this threshold.
