REF2025AISDDCR

The Texas Instruments REF2025AISDDCR is a high-precision, low-power voltage reference designed for demanding applications. It features two outputs, VREF and VREF/2, simplifying use in single-supply systems. The device boasts excellent temperature drift performance of 8 ppm/°C maximum across a wide operating range of -40°C to 125°C, coupled with a high initial accuracy of ±0.05% maximum.

With a low dropout voltage of just 10 mV and a high output current capability of ±20 mA, the REF2025AISDDCR is suitable for various power-sensitive designs. Its low quiescent current of 360 µA further enhances its suitability for battery-powered devices. The reference is available in a microsize SOT-23-5 package, making it ideal for space-constrained applications. A matte-tin version is also available for harsh environments.

Key electrical characteristics include low frequency noise of 30 µVPP (0.1 to 10 Hz), line regulation of 3 ppm/V, and load regulation of 8 ppm/mA. The device also offers VREF and VBIAS tracking overtemperature, with a maximum of 6 ppm/°C from -40°C to 85°C and 7 ppm/°C from -40°C to 125°C. An enable pin is included for power management.
