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. 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

2. What are the three types of voltage regulator?
The three types of voltage regulators include the contact voltage regulator, the transistor regulator and the integrated circuit regulator.
Contact voltage regulator: This is the type of voltage regulator used earlier. Its working principle is based on the vibration of the contact, but there is mechanical inertia and electromagnetic inertia, resulting in low voltage adjustment accuracy. Large, poor reliability, and short life, so it has been eliminated.
Crystal tube regulator: With the development of semiconductor technology, the transistor regulator becomes the mainstream. It uses a triode for voltage adjustment. Compared with the contact -type voltage regulator, the advantages of the transistor regulator is that the response speed, high efficiency, small volume, light weight, and not easily affected by external magnetic fields are widely used.
Integrated circuit regulator: Integrated circuit regulator is a new type of voltage regulator developed in recent years. It integrates mult

3. What is the minimum input voltage of a linear regulator?
The minimum input voltage range of linear regulator varies from model and application.
For certain low -voltage lower -voltage regulators, its minimum input voltage range is usually 2.5V to 2.7V. This type of regulator design is used to power the internal LDO drive circuit and can drive PMOS FET to provide high output current. However, when the output voltage is lower than 1.8V and the output current is greater than 2.5A, the linear regulator with PMOS bypass components may be used for external heat dissipation due to additional air flow requirements and/or the heat generated by the regulator. It becomes inconvenient and the cost will increase.
For universal linear stabilizers, its input voltage range can be very wide. For example, some general -purpose linear regulators have 3V to 40V input voltage range. Even for models suitable for 24V systems, the input maximum voltage can reach 60V Then, then
In summary, the minimum input voltage of the linear regulator does not have a fixed st
