KF25BD-TR Classification

PMIC - Voltage Regulators - Linear

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.

FAQ about PMIC - Voltage Regulators - Linear

  • 1. What problems will linear regulators bring to the circuit?

    The problems that linear regulators bring to the circuit mainly include low efficiency and a lot of heat.
    Linear The main working principle of the voltage regulator is to control the output voltage of the transistor through a current amplifier to keep the output voltage stable. This working mode causes the linear regulator to control the regulating tube through a differential voltage when adjusting the output voltage. The control tube needs to absorb part of the input voltage, which makes the efficiency of the linear regulator relatively low. In practical applications, this means that the linear regulator will convert the difference between the input voltage and the output voltage into heat energy, causing serious heating of the device, especially when the input and output voltage difference is large, this power loss will further increase, causing the device to heat up.

  • 2. Do linear regulators need capacitors?

    Linear regulators usually require capacitors.
    The working principle and design requirements of linear regulators determine that they usually require capacitors to ensure stable operation. These capacitors are mainly used to filter and stabilize the output voltage, help reduce output ripple and noise, and thus improve the stability and reliability of the power supply.
    Specifically:
    1. Input and output capacitors: Linear regulators usually require one or more input capacitors and one output capacitor. These capacitors help smooth the input and output voltages, reduce voltage fluctuations, and thus provide a stable output voltage.
    2. Power supply rejection capability: The power supply rejection capability of a linear regulator is an important indicator, which is related to whether it can effectively suppress unwanted signals and avoid interference with the output voltage. If the power supply rejection capability is poor, unnecessary signals may be left behind, affecting the purity of

  • 3. 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
