Voltage level conversion means convert a voltage level to another voltage level to establish safe communication or give a circuit desired power. If we want to establish a communication between 3.3V ESP32 with Arduino UNO which is 5V compatible we have use a voltage level converter.
https://en.wikipedia.org/wiki/Linear_regulator
Linear Voltage Regulator :
In electronics, a linear regulator is a system used to maintain a steady voltage. The resistance of the regulator varies in accordance with the load resulting in a constant output voltage. The regulating device is made to act like a variable resistor, continuously adjusting a voltage divider network to maintain a constant output voltage and continually dissipating the difference between the input and regulated voltages as waste heat.
Switch Mode Voltage Regulator :
a switching regulator uses an active device that switches on and off to maintain an average value of output. Because the regulated voltage of a linear regulator must always be lower than input voltage, efficiency is limited and the input voltage must be high enough to always allow the active device to drop some voltage.
