Summary:
The Texas Instruments REF3433QDBVRQ1 is an automotive-qualified series voltage reference. It provides a stable 3.3V output with high accuracy and low temperature drift.

Description:
The Texas Instruments REF3433QDBVRQ1 is a low-drift, low-power, small-footprint series voltage reference designed for automotive applications. It offers a precise 3.3V output voltage with a maximum initial accuracy of ±0.05% and a maximum temperature coefficient of 6 ppm/°C.

This voltage reference operates over a wide input voltage range from 2.55V to 12V and can supply an output current of up to ±10 mA. It features a low quiescent current of typically 72 µA and a low shutdown current of 2.5 µA. The device also exhibits low output 1/f noise, with a typical value of 12.5 µVPP from 0.1 Hz to 10 Hz.

Designed for reliability, the REF3433QDBVRQ1 is AEC-Q100 qualified and operates within an ambient temperature range of -40°C to +125°C. It is available in compact SOT-23 (5 and 6-pin) and 8-pin VSSOP packages, suitable for surface mount applications.

Key electrical characteristics include ±0.05% initial accuracy, 6 ppm/°C temperature coefficient, and ±10 mA output current capability. The device is also Functional Safety-Capable, making it suitable for critical systems.
