Series Voltage Regulator Presentation

Introduction to Series Voltage Regulator
A series voltage regulator is a type of electronic circuit used to regulate the output voltage of a power supply. It operates by using a series pass transistor to control the current flowing through a load resistor. The series voltage regulator is commonly used in applications where a stable and regulated voltage is required.	Image Source

Basic Operation of a Series Voltage Regulator
The input voltage is connected to the input of the series voltage regulator. The series pass transistor acts as a variable resistance, controlling the voltage across the load resistor. The feedback mechanism compares the output voltage with a reference voltage and adjusts the series pass transistor accordingly to maintain a stable output voltage.	Image Source

Disadvantages of Series Voltage Regulator
Inefficient due to the voltage drop across the series pass transistor, resulting in power dissipation and heat generation. Limited voltage regulation range as the output voltage cannot be higher than the input voltage. Not suitable for high power applications as the series pass transistor may require additional heat sinking.	Image Source
