VRE310BD is an application field and working principle of PMIC voltage reference. It is a single-channel, external reference voltage regulator with very low quiescent current, low dropout voltage, and high accuracy. It is ideal for dissipative systems that need to maintain accuracy and reliability in supply voltage regulation.

The VRE310BD has a wide range of adjustable voltages, from 0.6V to 1.9V. It also has low temperature drift, enabling excellent power train stability and improved application reliability. The device can be operated with a variety of power supplies, such as a switch-mode power supply, linear regulator, or battery.

The VRE310BD operates on the quasi-linear principle, which simplifies the control circuit design. The slope of the output voltage increases with a decreasing load current, and vice versa. This improves the regulation of the output voltage when the load and/or supply voltage changes. The output voltage remains relatively constant over temperature changes with a maximum variation of 0.2%/°C.

The output voltage is controlled by a single external resistor and the output voltage is adjustable from the programmed reference voltage. Internal protection features include overtemperature protection and latch protection. This prevents accidental damage due to incorrect use. The device also has an additional input for remote sensing, which helps compensate for voltage losses due to line resistance.

The VRE310BD is an ideal power regulator for applications such as computer motherboards, graphics cards, digital TVs, set-top boxes, audio amplifiers, gaming systems, and more. It is well suited for applications where high accuracy and stability is needed, and could benefit greatly from the VRE310BD’s low dropout voltage, low temperature drift and low quiescent current.
