REF35330QDBVR

Overview

The REF35330QDBVR is a nanopower, high-precision series voltage reference from Texas Instruments. It provides a fixed 3.3V output with ±0.05% initial accuracy and a maximum temperature coefficient of 12ppm/°C over the -40°C to 105°C range. The device operates on an input voltage ranging from VREF + VDO up to 6V. It features ultra-low quiescent current of 650nA typical in active mode and includes an enable pin for shutdown control. The component is housed in a compact 6-pin SOT-23 package.

Procurement Notes

Verify the specific ordering suffix matches the required package and temperature grade. Confirm that the 3.3V output variant is available in the SOT-23-6 package as specified. Ensure compatibility with system input voltage requirements relative to the dropout voltage. Check for moisture sensitivity level constraints during assembly.

Selection Notes

Select this part when a fixed 3.3V reference is required with high accuracy and minimal power draw. Consider the SOT-23-6 package for space-constrained designs. Evaluate the need for the enable pin functionality if power management is critical. Verify that the load regulation and line regulation specifications meet the application's stability requirements.

Part Context

This component belongs to the REF35 family of ultra-low-power, high-precision voltage references. The family offers various output voltages and package options, including SOT-23 and WCSP. The REF35 series is designed for portable and low-current applications requiring stable reference voltages for sensors and data converters.

Replacement Considerations

Other members of the REF35 family may serve as alternatives if different output voltages or packages are acceptable. Verify electrical characteristics and pinout compatibility before substitution.
