NSREF3020-DSTR

Overview

The NSREF3020-DSTR is a precision bandgap voltage reference IC from NOVOSENSE, delivering a nominal output of 2.048 V in a compact SOT-23-3L package. It operates with an input voltage range extending up to 5.5 V and maintains high accuracy within a maximum tolerance of 0.2%. The device features a low temperature coefficient of 35 ppm/°C across the -40°C to +125°C range and supports bidirectional output currents of ±10 mA. Designed for minimal power consumption, it exhibits a quiescent current of approximately 165 μA and achieves a dropout voltage as low as 1 mV.

Feature Summary

• Delivers precise 2.048 V reference output with 0.2% maximum initial accuracy.
• Maintains stable performance with a maximum temperature drift of 35 ppm/°C.
• Supports sourcing and sinking up to ±10 mA without requiring external load capacitors.
• Operates with ultra-low dropout voltage of 1 mV above the output level.

Applications

• Data acquisition systems
• Medical equipment
• Hand-held test equipment

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity of 3000 units per reel. Confirm that the component meets RoHS compliance standards and JEDEC peak reflow temperature classifications. Ensure the selected part number corresponds to the correct marking code for identification purposes during assembly.

Selection Notes

Select this component when a stable 2.048 V reference is required in space-constrained designs. Consider the low quiescent current for battery-powered applications where minimizing power dissipation is critical. Evaluate the ±10 mA output capability against system load requirements to ensure sufficient drive strength without external buffering.

Part Context

This device belongs to the NSREF30xx series of low-power, low-dropout precision bandgap references manufactured by NOVOSENSE. The series includes variants with different nominal output voltages, all sharing the same SOT-23-3L footprint and thermal characteristics. This family is designed to provide reliable voltage references for analog signal conditioning and measurement circuits.

Replacement Considerations

Compatible substitutes within the same series include NSREF3012-DSTR, NSREF3025-DSTR, NSREF3030-DSTR, NSREF3033-DSTR, and NSREF3040-DSTR. These parts share identical pin configurations and package dimensions but offer different nominal output voltages ranging from 1.25 V to 4.096 V.
