REF5025SKGD1 is a Low Drift Low Noise Precision Voltage Reference that is part of the Voltage Reference category of PMIC (Power Management Integrated Circuit). This integrated circuit is available in a small surface mount package that’s only 2.5mm tall by 1.5mm wide, making it compact yet reliable. Overall, this voltage reference is designed to meet a variety of needs across many market sectors.

REF5025SKGD1 has a wide variety of applications, particularly in products where long-term stability and accuracy is key. These applications can range from a wide selection of industrial, automotive, and medical work, as well as metering, process control, and test & measurement equipment. The integrated circuit is also an ideal choice for use in a wide variety of communication and audio systems, as well as different portable electronic products.

The voltage reference offers high-temperature stability, which is a key attribute for its massive array of potential applications. The tightly regulated 1.25V output voltage of the reference further attests to its reliability when it comes to stabilizing voltage levels. With its low drift rate, the reference is able to keep its output voltage from fluctuating excessively even under extreme temperatures.

When it comes to maximum current draw, the integrated circuit ensures reliable performance with an unrestricted maximum current that exceeds 10mA. This allows for the output voltage to remain stable during initial start-up, and any sudden changes in current demand by other components.

REF5025SKGD1’s wide variety of features is complemented by its cost-effectiveness and energy efficient power consumption. As with most analog integrated circuits, the device operates on a single, positive supply rail that’s generally rated between 3V. and 5.5V. As for current draw, the operational and shut-down current draw are rated at 10µA and 6µA respectively.

The low temperature co-efficient of the integrated circuit adds to its accuracy and stability, with the output voltage of the reference remaining constant for an array of temperatures. With its admirable temperature stability, the device is an ideal choice for applications where reliability and accuracy are of the utmost priority, such as medical and military work.

The working principle of the REF5025SKGD1 is based on the fact that it utilizes a buffer amplifier for stable and accurate voltage reference. This buffered amplifier stabilizes the voltage during transient changes in voltage. The voltage reference used in the integrated circuit is then connected to a voltage divider network. This network allows for the selection of the desired output voltage by connecting a resistor to the device’s 2 reference terminals.

The combination of the buffered amplifier and the resistor divider is what enables the integrated circuit to maintain a steady and accurate output voltage regardless of any changes in the supply voltage. Ultimately, this results in the REF5025SKGD1 being a reliable low drift low noise precision voltage reference, making it a perfect choice for any application where stability and accuracy are of the utmost importance.
