PMIC - Voltage Reference products are used in a variety of applications and the most predominant use is to keep the voltage in a circuit within a predetermined window. The REF3130AIDBZR has a robust feature set and ease of use making it an ideal choice for most applications. This article will explain the application field and working principle of the REF3130AIDBZR in order to assist in the selection of this product.

The REF3130AIDBZR is a voltage reference that is designed for use in systems where high accuracy, low power consumption and precision operation are needed. It operates on a wide range of input voltages from 1.2V to 10V, and can output a voltage as low as 0.1V. The maximum output current is defined by a combination of the external resistor and capacitance network. It provides a precise voltage reference that is accurate to within 0.1%.

The REF3130AIDBZR is ideally suited for use in power management circuits that require precise reference voltages. It is often used in designs that involve battery charging, LED lighting, and power supply regulation, and can also be used in automotive and industrial applications. It is also well suited for low voltage processor cores and low voltage bus designs.

The REF3130AIDBZR has been designed to consume very low power, making it ideal for most battery-powered applications. The device can operate at a supply voltage of less than 1V and draws only 1 µA of current. This makes it suitable for low power, low voltage designs where other references would draw too much power. Additionally, the device has an wide operating temperature range from -40°C to 85°C.

When used as a voltage reference, the REF3130AIDBZR is connected in series with a load resistor to form a voltage divider. When the reference voltage is applied, the output voltage over the resistor is proportional to the reference voltage. When the reference voltage changes, the output voltage also changes proportionally. This variation in the output voltage is due to the fact that the REF3130AIDBZR is a Voltage Expression Device, meaning that the voltage across the device is proportional to the supply voltage. This means that when the supply voltage changes, the output voltage also changes proportionally.

The REF3130AIDBZR also includes a number of other features that make it an ideal choice for many power management and voltage reference designs. It includes protection circuitry on the input side of the device that prevents over-voltage and reverse leakage of current. In addition, the device includes optional shunt regulation that allows the user to adjust the reference voltage by varying the supply voltage. The device also features a thermal compensation feature that compensates for temperature variations and helps maintain the accuracy of the reference voltage.

In conclusion, the REF3130AIDBZR is an ideal choice for voltage reference applications where high accuracy and low power consumption are required. It offers a wide range of features and advantages, and is especially suited for power management and low power designs. As such, it should be a consideration for any power management or voltage reference application.
