NSREF3030-DSTR

Overview

The NSREF3030-DSTR is a precision bandgap voltage reference IC from the NSREF30xx series, manufactured by NOVOSENSE. It provides a fixed output voltage of 3.006 V with a maximum accuracy of 0.2%. The device operates within an input supply range of 1.8 V to 5.5 V and features a low dropout voltage of 1 mV. It delivers a load current capability of ±10 mA and maintains a quiescent current of approximately 145 µA. Key electrical specifications include a temperature coefficient of 35 ppm/°C over the -40°C to +125°C range and a peak-to-peak noise of 28 µV in the 0.1 Hz to 10 Hz bandwidth. The component is housed in a compact SOT-23-3L package.

Feature Summary

• Delivers high precision with 0.2% maximum initial accuracy and low temperature drift of 35 ppm/°C.
• Operates with minimal power consumption, featuring a low quiescent current of 145 µA and ultra-low dropout voltage.
• Provides robust output drive capability, sourcing or sinking up to ±10 mA without requiring external compensation capacitors for stability.
• Ensures long-term reliability with specified stability metrics and resistance to thermal hysteresis effects.

Applications

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

Procurement Notes

Verify that the specific part number NSREF3030-DSTR matches the required 3.006 V output voltage and SOT-23-3L package configuration. Confirm compliance with RoHS standards and check for any specific handling requirements related to electrostatic discharge sensitivity during assembly. Ensure the operating temperature range aligns with system constraints.

Selection Notes

Select this component when a stable 3 V reference is needed for battery-powered applications requiring minimal power dissipation. The low dropout characteristic allows operation close to the output voltage, while the ±10 mA current capability supports direct driving of moderate loads. Consider the 28 µVp-p noise specification for sensitive analog signal paths.

Part Context

The NSREF3030-DSTR belongs to the NSREF30xx family of low-power, low-dropout precision bandgap references. This series is designed for applications where small size and low power are critical. Other variants in the family offer different fixed output voltages, such as 1.25 V, 2.048 V, 2.5 V, 3.3 V, and 4.096 V, all sharing similar performance characteristics and packaging.

Replacement Considerations

Direct substitutes within the same family include NSREF3025-DSTR (2.5 V) and NSREF3033-DSTR (3.3 V), provided the voltage difference is acceptable for the application. Cross-manufacturer replacements require matching the 3 V output, SOT-23-3L package, and comparable accuracy and noise specifications.

FAQ

Does the NSREF3030-DSTR require an output capacitor for stability?

No, the NSREF30xx series does not require an output compensation capacitor to remain stable, although adding one can improve transient response.

What is the minimum supply voltage required for the NSREF3030-DSTR?

The minimum input supply voltage is VOUT + 0.05 V, which is approximately 3.05 V for this specific model.

How is the temperature coefficient defined for this device?

The temperature coefficient is calculated using the box method, representing the change in output voltage over the temperature range from -40°C to +125°C.
