NSREF3012-DSTR

Overview

The NSREF3012-DSTR is a precision bandgap voltage reference IC from the NSREF30xx series, manufactured by NOVOSENSE. It provides a fixed output voltage of 1.25 V with a maximum initial accuracy of 0.2%. The device operates within an input voltage range of 1.8 V to 5.5 V and supports a load current of ±10 mA. Key electrical specifications include a maximum temperature coefficient of 35 ppm/°C over the -40°C to +125°C range, a quiescent current of 165 µA (typical), and a low dropout voltage of 1 mV. The component is housed in a SOT-23-3L package.

Feature Summary

• Delivers high precision with a maximum initial accuracy of 0.2% and low temperature drift of 35 ppm/°C.
• Features ultra-low dropout capability, requiring only 1 mV headroom above the output voltage for stable operation.
• Ensures stability without the need for an external output compensation capacitor.
• Supports bidirectional sourcing and sinking of up to ±10 mA output current.

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 SOT-23-3L package dimensions align with the target PCB footprint. Ensure the operating environment stays within the specified -40°C to +125°C temperature range to maintain guaranteed performance parameters.

Selection Notes

Select this component when a low-cost, low-power reference is needed for battery-powered applications. The 1.25 V output is suitable for interfacing with ADCs requiring lower reference voltages. Consider the 165 µA quiescent current for power budget calculations. Verify that the 1 mV dropout requirement fits the minimum supply voltage constraints of the system design.

Part Context

The NSREF3012-DSTR belongs to the NSREF30xx family of precision voltage references designed for general-purpose signal chain applications. This series emphasizes low power consumption and small form factor integration. The DSTR suffix indicates the standard tape and reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

Other members of the NSREF30xx series, such as NSREF3020 or NSREF3025, share identical pinouts and functional characteristics but provide different fixed output voltages. Direct substitution requires verifying that the alternative voltage level meets the circuit requirements.
