Working Principle of AS78L15ZTR-E1

The AS78L15ZTR-E1 voltage regulator works by controlling the voltage at its output pin. This is done using a voltage reference voltage source, an error amplifier and a series pass element. The error amplifier examines the output voltage and compares it to the reference voltage and then adjusts the current through the series pass element accordingly in order to match the output voltage to the reference voltage. The voltage reference source can be either an internal reference voltage or an external voltage.

The advantages of this type of voltage regulator include stability, a wide range of input voltages and low output noise. In addition, the voltage regulator is designed to provide protection against excessive output current and thermal overload. Finally, it is designed to operate in low power environments and requires very little current to operate.
