REF35330QDBVR | REF35330 reference TI voltage reference ic 3.3V SOT-23
The REF35330QDBVR from Texas Instruments is a nanopower, high-precision 3.3V series voltage reference in a compact 6-pin SOT-23 (DBV) package, engineered for battery-powered and low-current precision measurement systems. As the 3.3V member of the REF35 family, it combines an ultra-low 650nA typical quiescent current with ±0.05% maximum initial accuracy, a 12ppm/°C maximum temperature drift (over -40°C to +105°C), and 3.3ppm peak-to-peak 1/f noise. The device sources up to +10mA (and sinks -5mA) from an input supply spanning 3.55V to 6V, and integrates a dedicated NR pin for external noise filtering plus an EN pin that drops shutdown current to near-zero. Specified for -40°C to +105°C operation and fully functional over -55°C to +125°C, it ships in RoHS3-compliant tape-and-reel format for automated SMT assembly.
Applications
Designed for flow transmitters, blood glucose monitors, servo drive control modules, power quality analyzers, fault indicators, oscilloscopes, process analytics, and optical modules, the REF35330QDBVR also excels as the reference supply for 12-16-bit ADCs and precision sensor bridges (RTDs, thermocouples, strain gauges) in battery-powered and industrial equipment where nanowatt-level power and low drift are mandatory.
Frequently Asked Questions
Q: What input voltage headroom is required? A: The input must be at least VREF + VDO (dropout voltage); for the 3.3V output, a minimum 3.55V input (with a 6V maximum) guarantees regulation.
Q: Is an output capacitor required for stability? A: TI recommends CL = 10µF at VREF plus 0.1µF at VIN per the datasheet, though the device tolerates a range of ceramic and tantalum values.
Alternative / Replacement Voltage Reference Models
● MAX6035AAUT33+T (Analog Devices): Micropower 3.3V series voltage reference in SOT-23-3 with ±0.2% initial accuracy and 7ppm/°C drift, a classic pin-similar upgrade path.
● ADR3433BRJZ (Analog Devices): 3.3V precision reference featuring ±0.1% accuracy, 8ppm/°C drift, and rail-to-rail output in SOT-23-3.
● LM4132 (Texas Instruments): Legacy SOT-23 precision low-dropout reference family (now obsolete) that the REF35 family supersedes with lower quiescent current.
● REF30330AIDBZR (Texas Instruments): Lower-cost 3.3V series reference with 50ppm/°C drift and 42µA quiescent current for budget-sensitive designs.
