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. 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 -
3. Which is better, switching power supply or linear regulator?
Switching power supply and linear regulator each have their advantages and disadvantages, and choosing which one is better depends on the specific application requirements.
The main advantages of switching power supply include:
High efficiency: The conversion efficiency of switching power supply can reach 90%~95%, which is much higher than the 30% or so of linear regulator.
Small size and light weight: Due to the high efficiency and high-efficiency transformer of switching power supply, large heat sink can be omitted, and high-frequency transformer replaces power frequency transformer, greatly reducing volume and weight.
Wide voltage regulation range: The output voltage of switching power supply can compensate for the change of input voltage by adjusting the duty cycle to ensure stable output voltage.
Various circuit forms: Designers can design switching power supplies that meet the needs according to different application scenarios.
However, switching power supplies also have so
