FAQ about PMIC - Voltage Regulators - Linear

1. 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.

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 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
