Analog Devices LDO: Is it okay to use a resistor in series from the voltage source to the input of the LDO to spread the power consumption?
The inquiry method is an effective way to reduce the power consumption of the LDO and lower the junction temperature when the input voltage is high.
At this time, calculate the resistance value so that the IR (current * resistance value) drop due to the inserted resistance does not fall below the minimum operating voltage of the LDO and the output voltage + drop voltage.
