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.

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.

• 1. When should a linear regulator be used instead of a switching regulator?

  In low-power and low-frequency application scenarios, a linear regulator should be used instead of a switching regulator.
  Linear regulator Suitable for low-power and low-frequency applications, with simple circuit structure, low noise and good stability. They control the output voltage of the transistor through a current amplifier to keep the output voltage stable. This working mode makes linear regulators perform well in low-power and low-frequency applications, although they are less efficient and generate more heat, and their application range is limited. In contrast, switching regulators use high-frequency pulse modulation technology to convert input voltage into a stable output voltage. They have the advantages of high efficiency, small size and fast response, and are suitable for high-power and high-frequency applications. Therefore, when the application requirements are not the main considerations for circuit complexity and cost, but have high requirements for the stability and

• 2. How to choose a linear regulator?

  1. Switching regulator: A switching regulator uses an output stage that repeatedly switches between "on" and "off" states to generate an output voltage together with an energy storage component. Its adjustment is achieved by adjusting the switching timing based on the feedback sample of the output voltage. In a fixed-frequency regulator, the switching timing is adjusted by adjusting the pulse width of the switching voltage, which is called PWM control.
  2. Parameter regulator: LDO is a linear regulator. Linear regulators use transistors or FETs operating in their linear region to subtract excess voltage from the applied input voltage to produce a regulated output voltage. This transistor allows saturation, so the regulator can have a very low dropout voltage, usually around 200mV.
  3. Regulators for laser cutting machines: According to the use requirements of high-power laser cutting machines and the current power supply situation in my country, regulators that meet

• 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
