Overview
The REF35250QDBVRQ1 is an automotive-grade, ultra-low-power, high-precision voltage reference with a fixed 2.5 V output. It features ±0.05% initial accuracy and a maximum temperature coefficient of 15 ppm/°C over the -40°C to +125°C range. The device draws a typical quiescent current of 650 nA in active mode and supports up to 10 mA sourcing and 5 mA sinking load currents. It includes an enable pin for shutdown control and a noise reduction pin.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Ultra-low power consumption with nanowatt-level quiescent current
- High precision performance with minimal voltage drift across temperature ranges
- Integrated enable functionality to reduce shutdown current consumption
Applications
- Automotive front camera systems
- Driver monitoring systems

Procurement Notes
Verify that the specific part number suffix matches the required output voltage and package configuration. Confirm that the component meets the necessary AEC-Q100 grade requirements for your specific automotive application environment. Ensure compatibility with your system's input voltage and load current specifications before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring high precision and low power consumption in automotive environments. Consider the 2.5 V output level and the ability to source up to 10 mA for driving sensors or data converters. Evaluate the need for the enable pin feature if power management during inactive states is critical for the system design.
