PMIC - Voltage Reference is a type of power management integrated Circuit (IC) which is used to maintain a predetermined stable voltage. VRE305LS is a monolithic positive voltage regulator for mobile application, which is operated with an output voltage of 3V and is compliant to AEC-Q100 Level 1.

In the application field, VRE305LS can be used in various industries. It is particularly suitable for next-generation mobile display, wearable displays, automotive display and car DVD players. Its power circuit design provides efficient current-limit and over-temperature protection, making it suitable for battery-powered systems.

The working principle of the VRE305LS is similar to that of other voltage regulators. Initially, the voltage is supplied through the input register to the power stage, then is stepped down to the required level, and finally is stabilized at the output register. This type of regulator integrates various components with the same power supply, which is then shared by main power stages, control signals and other transistors, resistors and capacitors to help minimize power consumption.

In addition, the VRE305LS has a control loop function, which is passed by the control signal and rectified by the error amplifier. When the output voltage is too high, the error amplifier will send a signal to the operation amplificator to reduce the current, and vice versa. The output voltage will be stabilized after multiple loops.

In conclusion, VRE305LS is a monolithic positive voltage regulator with an output voltage of 3V and is compliant to AEC-Q100 Level 1. It is suitable for various mobile displays, automotive displays and DVD players due to its efficient current-limit protection and over-temperature protection. It works with a control loop function, which provides a regulated output voltage to keep the device running in a safe condition.
