Introducing the REF02EP+ Precision Voltage Reference from Maxim Integrated

The REF02EP+ is a high-precision voltage reference component designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering. This exceptional device provides a stable and precise 5V output, which can be adjusted over a ±1% range with minimal external components. Its impressive temperature coefficient of only 10ppm/°C (max) over the full industrial temperature range ensures reliable performance under varying conditions.

Engineered for versatility, the REF02EP+ is suitable for a wide array of applications. It is commonly used in 8-bit and 16-bit microcomputers, A/D and D/A converters, digital voltmeters, battery chargers, and power supplies. Its low quiescent current of 1.4mA (max) makes it an excellent choice for battery-operated equipment, where power conservation is critical.

One of the standout features of the REF02EP+ is its excellent load and line regulation capabilities. With a load regulation of 0.2mV/mA (max) and a line regulation of 0.01%/V (max), it ensures that the output voltage remains stable despite changes in load current or supply voltage. This stability is crucial for precision applications where voltage fluctuations can lead to inaccurate readings or system malfunctions.

The REF02EP+ also features a low noise output, with a typical noise voltage of only 15µVp-p (10Hz to 10kHz), providing a clean reference signal for sensitive electronic circuits. Additionally, the device includes a 30mA output source and sink capability, which is sufficient for most reference applications.

For ease of integration into various circuit designs, the REF02EP+ is available in an 8-pin DIP or SO package. Its industry-standard pinout makes it a drop-in replacement for many other 5V references, simplifying the upgrade process for existing designs. With its combination of precision, stability, and flexibility, the REF02EP+ is an ideal choice for engineers seeking a reliable voltage reference for their next project.

Maxim Integrated's commitment to quality ensures that the REF02EP+ meets the highest standards, providing designers with confidence in the performance and longevity of their electronic systems.
