An LDO (Low Dropout) voltage regulator is a type of linear regulator that can maintain a stable output voltage even when the difference between the input and output voltage is small. It is characterized by its low dropout voltage, which makes it particularly useful in battery-powered or low-voltage applications where efficient use of the available input voltage is important.
It is important to note that the voltage regulator operates linearly – all excess power is dissipated as heat, which means a heatsink may be required in some cases. A general rule for power loss is: P tot = (V in - V out) * I out
