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 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

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. Can a linear regulator be up?
Linear regulators cannot be boost.
The main function of a linear regulator is to stabilize the output voltage, protecting the electrical equipment from high or unstable voltage effects. It realizes a stable output voltage by adjusting the gap between the output voltage and the input voltage, but this process is limited to lowering the voltage, not including the voltage. The working principle of a linear regulator is to regulate the voltage by converting excess voltage into heat loss, thereby realizing the voltage regulation. This feature determines that it does not have the voltage function.
