PMIC - Voltage Regulators - Linear

What is a linear regulator?

Voltage regulators are integrated circuits that create a constant and steady voltage in a circuit. They convert a variable input voltage to a set output voltage. The regulator will continue to deliver the same output regardless of the input voltage. The output voltage is compared to a reference value by the linear voltage regulator. The pass device will then be adjusted to assist regulate the output voltage. Depending on where the voltage regulator(s) are located, this helps to regulate the voltage throughout a circuit design.

Voltage regulators are critical components in electrical circuits that require a specific voltage input. Take, for instance, a processor. When selecting a voltage regulator IC, the input voltage, output voltage, and output current are all significant factors to consider. Voltage regulators, for example, cannot transfer voltage from AC to DC. Please visit our Digital to Analogue Converters (DACs) or Analogue to Digital Converters (ADCs) if you need voltage conversion in parallel with your voltage regulator (ADCs).

What are the most used types of regulators? 

• Switching Regulator with Buck-Boost
• Pump Charge
• Regulator of Linear Voltage
• Voltage Regulator with Low Dropout (LDO)

Where are the regulators used?

Electronic regulators are used to regulate the DC voltages utilized by the CPU and other components in devices such as computer power supplies. Voltage regulators govern the output of generator plants in automotive alternators and central power plants. Most electronics circuits that require voltage control or regulation have regulators. Chargers, power supply units (PSUs), telecommunications, and automotive applications are all examples.

A linear regulator is probably required in more than 90% of products, making it one of the most widely used electrical components. A voltage regulator is essential unless everything can be powered directly from the battery or an external AC/DC adaptor. 

What are the Most Used Regulator Types?

Shunt and series regulators are the two types of regulators. The rated output current of most regulators is limited. This is usually restricted by either the output transistor's power dissipation capabilities or its current-carrying capability.

Shunt Regulator 

The shunt regulator operates by providing a variable resistance channel from the supplied voltage to the ground (the main transistor is in the "bottom half" of the voltage divider). Because the current in a shunt regulator is redirected away from the load and flows directly to the ground, it is often less efficient than a series regulator.

Series Regulator 

The most frequent kind is a series regulator, which is more efficient than a shunt arrangement. The series regulator provides a conduit from the supply voltage to the load through a variable resistance, generally a transistor (known as the series pass transistor in this position); it is in the "upper half" of the voltage divider, with the load in the bottom half.
