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 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 are the disadvantages of linear regulators?
The disadvantage of linear regulators is that they are not efficient and can only be used in voltage reduction applications. The efficiency of a linear regulator depends on the ratio of output voltage to input voltage: turbidity = Vo: Vi. For example, for ordinary linear regulators, when the input voltage is 5V and the output voltage is 2.5V, the efficiency is only 50%. For ordinary linear regulators, about 50% of the electrical energy is converted into "heat" and lost, which is also the main reason why ordinary linear regulators are prone to heat when working. For LDO, due to its low voltage difference, the efficiency is much higher. For example, when the input voltage is 3.3V and the output voltage is 2.5V, its efficiency can reach 76%. Therefore, in LCD color TVs, in order to improve the utilization rate of electrical energy, ordinary linear regulators are used less, while LDOs are used more.

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.
