PMIC - Voltage Regulators - Special Purpose are devices specifically designed to convert input voltages into output voltages. They maintain voltage output at a specific value at dynamic load and source voltage changes, and the phenomenon is known as regulation. Special purpose regulators have dedicated regulators for specific applications with varied features and functionalities according to the application requirements. These regulators of special purpose type, include variable voltage regulators, shunt voltage regulators, alternate voltage regulators, and more.

What is a Voltage Regulator?
As the name indicates, voltage regulators regulate the voltage, irrespective of the input voltage or connected load adjustments. They protect the devices from damage and work as a shield. Based on the design, they can regulate both AC and DC voltages.
Types of Voltage Regulators
Voltage regulators employed in low-voltage systems are generally integrated type circuits. They are divided into two main types: Linear voltage regulators; which are further sub-divided into two types, i.e., series and shunt, and Switching voltage regulators; which are further divided into the step up, step down, and inverter voltage regulators.
Linear Voltage Regulators
The Linear regulators are original regulators that function as a voltage divider that uses FET In the Ohmic region. They regulate the power supply and are ideal for various applications—the voltage regulators’ resistance changes with power variation, resulting in a constant output voltage.
Switching Voltage Regulators
A switching regulator is designed to switch ON and OFF a series of devices efficiently. The duty cycle of the switch sets the amount of charge transmitted to the load. They are robust devices that dissipate no power as the series element is switched off. A feedback mechanism like linear regulators regulates them. In addition, they generate higher output voltages than input voltages, similar to linear regulators.
