TPR5025-SO1R

Overview

The TPR5025-SO1R is a fixed-output voltage reference IC from the TPR50 series, manufactured by 3PEAK. It provides a nominal output voltage of 2.5 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 3 V to 15 V and supports bidirectional current sourcing and sinking of ±10 mA. Key electrical characteristics include a typical temperature coefficient of 2.5 ppm/°C over the -40°C to 125°C range and low output noise of 3 μVpp/V in the 0.1 Hz to 10 Hz band. It is housed in an 8-pin SOP package.

Feature Summary

• High precision with 0.05% maximum initial accuracy and low temperature drift for stable reference performance.
• Bidirectional output capability supporting both sourcing and sinking currents up to ±10 mA.
• Integrated noise reduction pin allows for additional filtering to minimize output noise levels.

Applications

• Battery test equipment
• Industry control systems
• Precision instrumentation
• Medical equipment

Procurement Notes

Verify the specific part number suffix against the manufacturer's datasheet to confirm package type and output voltage. Ensure compatibility with system thermal requirements, as junction temperature depends on power dissipation calculations. Confirm moisture sensitivity level (MSL 3) handling procedures during assembly. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a fixed 2.5 V reference with high initial accuracy is required. Consider the ±10 mA load capability for driving downstream circuits without external buffering. Evaluate the thermal resistance characteristics if operating near temperature extremes. Verify that the input voltage remains within the specified 3 V to 15 V range for proper regulation.
