Frequently Asked Questions
What is the input voltage range supported by REF2033QDDCRQ1?
REF2033QDDCRQ1 accepts input voltages from 2.52 V minimum to 5.5 V maximum, making it compatible with 3.3 V and 5 V single-supply systems. This wide range allows it to operate directly from common logic supply rails without a pre-regulator, simplifying the overall power architecture in embedded and automotive designs.
How much output current can REF2033QDDCRQ1 supply to a load?
The device can source up to 20 mA of output current, providing enough drive capability to power ADC reference inputs and precision sensor circuits simultaneously. At lighter loads the quiescent current remains low, which is important for battery-operated systems where every milliamp matters in extending runtime.
Which automotive applications benefit most from using REF2033QDDCRQ1 in an AEC-Q100 design?
Automotive body-control modules, ADAS sensor front-ends, and in-vehicle battery-management units benefit from REF2033QDDCRQ1 because it is AEC-Q100 qualified and provides a stable 3.3 V reference across the -40 °C to +125 °C automotive temperature range. Its 5-pin SOT-23 package minimises PCB area in space-constrained ECU designs.
