TPR7025-SO1R

Overview

The TPR7025-SO1R is a precision voltage reference from the TPR70 series, manufactured by 3PEAK. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 7.5 V to 15 V and supports both sourcing and sinking currents up to ±10 mA. It features a typical temperature coefficient of 1 ppm/°C over the -40°C to 125°C range and exhibits low noise characteristics. Packaged in SOP8, it is designed for high-resolution systems requiring stable reference voltages.

Feature Summary

• High-precision voltage reference with 0.05% maximum initial accuracy
• Low temperature drift performance suitable for wide operating ranges
• Capable of sourcing and sinking ±10 mA output current
• Includes dedicated noise reduction pin for enhanced signal integrity

Applications

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

Procurement Notes

Verify the specific package type (SOP8) and output voltage (2.5 V) against project requirements. Confirm that the supply voltage remains within the 7.5 V to 15 V operational limits. Ensure thermal management aligns with the specified junction temperature ratings. Check for RoHS compliance and halogen-free status if required by environmental standards.

Selection Notes

Select this component when a stable 2.5 V reference is needed with high accuracy and low drift. Consider the ±10 mA current capability for driving loads directly. Evaluate the need for external noise reduction capacitors on the NR pin. Compare thermal resistance values against available PCB space for heat dissipation.

Part Context

This part belongs to the TPR70 family of low-noise, low-drift precision voltage references. Other members include TPR7020, TPR7030, and TPR7050, offering different fixed output voltages. All share similar electrical characteristics and packaging options, allowing for design flexibility across various voltage requirements within the same product line.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other TPR70 series variants or comparable high-precision references ensuring matching output voltage, accuracy, and package dimensions.
