TPR5012-SO1R

Overview

The TPR5012-SO1R is a high-precision, low-drift voltage reference from the TPR50 series by 3PEAK. It provides a fixed output voltage of 1.25 V with an initial accuracy of ±0.05% and a typical temperature coefficient of 2.5 ppm/°C across the -40°C to +125°C range. The device supports ±10 mA sourcing and sinking currents with a dropout voltage as low as 200 mV at ±5 mA. Operating input voltage ranges from 3 V to 15 V, while quiescent current is typically 1 mA. Noise performance is specified at 3 μVpp/V in the 0.1 Hz to 10 Hz band.

Feature Summary

• Features a dedicated noise reduction pin for additional filtering capability
• Supports bidirectional current flow with both sourcing and sinking capabilities up to ±10 mA
• Provides long-term stability data verified over extended operational hours

Applications

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

Procurement Notes

Verify the specific package marking code R5A against official documentation to confirm authenticity. Ensure the component meets MSL Level 3 requirements for moisture sensitivity during storage and handling. Confirm that the supply chain source adheres to RoHS compliance standards as defined by the manufacturer's green product specifications.

Selection Notes

Select this component when a stable 1.25 V reference is required for high-resolution applications. Consider the SOP8 package dimensions and thermal resistance values if heat dissipation is a concern. Evaluate the need for external capacitors on the NR/TR pin to optimize noise performance based on specific circuit requirements.
