Voltage Regulators-Linear is an electronic device used to convert an unstable DC voltage into a stable DC voltage. It regulates the voltage through an active component (such as a transistor or field effect tube) and a feedback network to ensure that the output voltage remains constant within a certain range. Linear regulators usually operate under low input voltage changes and load changes, and are able to provide a very clean and smooth output voltage.
Application
Voltage Regulators-Linear has a wide range of applications, covering almost all electronic devices requiring a stable DC power supply. In the field of consumer electronics, linear voltage regulators are widely used in mobile phones, tablets, laptops and other portable devices to provide stable voltage support for core components such as processors, memory and display screens. In the field of industrial automation and instrumentation, linear voltage regulators are often used in precision measuring instruments, sensor signal processing and other occasions because of their low noise and high precision characteristics. In addition, linear regulators also play an indispensable role in areas such as medical equipment, aerospace, and automotive electronics, where the quality of the power supply is extremely high. For example, in medical equipment, linear regulators ensure the power stability of devices such as pacemakers and monitors, ensuring the safety of patients.
FAQ about PMIC - Voltage Regulators - Linear

1. What is a linear regulator?
A linear regulator is an electronic device that is primarily used to maintain a specified output voltage stable when the input voltage or load conditions change. It is an important component in electronics that acts as a buffer to protect the components of the circuit from damage. A linear regulator works by using an active device (such as a BJT or MOSFET) controlled by a high-gain amplifier, using the variable conductivity of the active pass device to maintain the output voltage. This regulator acts as a voltage divider to produce a regulated output voltage, where a linear element (such as a resistive load) is used to regulate the output voltage. The transistor stays in its active region of operation during voltage regulation. To maintain a constant output voltage, the internal resistance can be varied, providing a variable resistance by using a transistor controlled by the amplifier feedback loop.
A linear regulator is also called a buck converter, where the output voltage is always

2. Which is better, switching power supply or linear regulator?
Switching power supply and linear regulator each have their advantages and disadvantages, and choosing which one is better depends on the specific application requirements.
The main advantages of switching power supply include:
High efficiency: The conversion efficiency of switching power supply can reach 90%~95%, which is much higher than the 30% or so of linear regulator.
Small size and light weight: Due to the high efficiency and high-efficiency transformer of switching power supply, large heat sink can be omitted, and high-frequency transformer replaces power frequency transformer, greatly reducing volume and weight.
Wide voltage regulation range: The output voltage of switching power supply can compensate for the change of input voltage by adjusting the duty cycle to ensure stable output voltage.
Various circuit forms: Designers can design switching power supplies that meet the needs according to different application scenarios.
However, switching power supplies also have so

3. What is the difference between a linear regulator and a resistor?
Linear regulators and resistors have significant differences in function, working principle and application scenarios.
Function and working principle:
A linear regulator is an electronic device that achieves a stable voltage output by adjusting linear elements (such as resistors, transistors, etc.) in the circuit. It uses the negative feedback principle. When the input voltage changes, the regulator senses this change and adjusts the parameters of the circuit elements (such as the resistance value or the conduction state of the transistor) accordingly to keep the output voltage stable within the required range. Linear regulators can provide lower output noise and fluctuations, and have better responsiveness to load changes.
Resistors are a basic electronic component used to limit current and divide voltage. It works by hindering the flow of current, has a fixed resistance value, and does not have the function of adjusting the output voltage.
