Procurement Notes

Verify the specific part number NSREF3033-DSTR against official NOVOSENSE documentation to confirm the 3.3V output variant and SOT23-3L package configuration. Ensure that design requirements align with the specified electrical characteristics, including the 0.2% accuracy and 35 ppm/°C temperature drift limits. Confirm compliance with RoHS standards and JEDEC peak reflow temperature classifications during procurement planning.

Selection Notes

Select the NSREF3033-DSTR when a stable 3.3V reference is required in space-constrained designs utilizing the SOT23-3L package. This component is appropriate for applications demanding low power consumption and high accuracy without the complexity of external stabilization capacitors. Consider the ±10mA drive capability and low dropout performance for systems with varying supply voltages or significant load transients.

Part Context

The NSREF3033-DSTR belongs to the NSREF30xx family of precision low-power series voltage references developed by NOVOSENSE. This family includes variants with different nominal output voltages, such as 1.25V, 2.048V, 2.5V, 3.0V, and 4.096V. All members share common architectural features, including bandgap reference technology, low dropout operation, and robust performance over the industrial temperature range.

Replacement Considerations

Other members of the NSREF30xx series, such as NSREF3030-DSTR (3.0V) or NSREF3040-DSTR (4.096V), share identical pinouts and package dimensions but provide different nominal output voltages. Substitution requires verifying that the system can tolerate the alternative reference voltage level.
