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. What are the characteristics of linear regulators?

  Linear regulators have the characteristics of low cost, small package, few peripheral devices and low noise. There are many types of linear regulator packages, which are very suitable for use in LCD color TVs. For fixed voltage output applications, only 2-3 small capacitors are needed to form the entire solution. Ultra-low output voltage noise is the biggest advantage of linear regulators. The output voltage ripple is less than 35V (RMS), and it has an extremely high signal-to-noise control ratio, which is very suitable for powering small signal processing circuits that are sensitive to noise.

• 2. What is the difference between linear regulators and switching regulators?

  There are significant differences between linear regulators and switching regulators in terms of working principles, efficiency, stability, cost and application range.
  Working principle:
  Linear regulators achieve the function of stabilizing the output at a set value by adjusting the voltage difference between the output voltage and the input voltage. It achieves stable output voltage by controlling the conductivity state of the power transistor.
  The switching regulator converts the input voltage into a pulse signal transmission and smoothes the output through a filter by quickly switching between the input and output ends to achieve the function of stabilizing the output at the set value. The switching regulator uses PWM (pulse width modulation) control to control the output voltage by adjusting the time duty ratio of the high and low levels within a cycle.
  Efficiency:
  The efficiency of the linear regulator is relatively low, usually between 60% and 70%. When the voltage differenc

• 3. 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
