REF1925AIDDCR Description

Short technical summary and product information.

The Texas Instruments REF1925AIDDCR is a precision, low-power, dual-output voltage reference IC. It provides a stable 2.5V reference voltage (VREF) and a VREF/2 output, making it suitable for single-supply systems requiring a voltage rail in the middle.

 

Key electrical specifications include a high initial accuracy of ±0.1% maximum and a low temperature coefficient of 25 ppm/°C maximum over the operating range of -40°C to 125°C. The device boasts a low dropout voltage of 10 mV and can supply up to ±20 mA of output current. Its low quiescent current is typically 360 µA, with a shutdown current of only 3.3 µA.

 

Designed for convenience and performance, the REF1925AIDDCR features an enable pin for power management. Its VREF and VBIAS tracking over temperature is excellent, with a maximum of 6 ppm/°C from -40°C to 85°C and 7 ppm/°C from -40°C to 125°C. Line regulation is 3 ppm/V and load regulation is 8 ppm/mA.

 

The component is housed in a micro-size SOT-23-5 package, measuring 8.12 mm² (2.9 mm x 2.8 mm), suitable for space-constrained applications. The mounting type is surface mount.
