TPR5012-VS1R-S

Overview

The TPR5012-VS1R-S is a high-precision, low-temperature-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%. The device operates within a wide input voltage range of 3 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 (0°C to 70°C) and 2.5 ppm/°C (-40°C to 125°C). The component is housed in an MSOP-8 package and functions across a junction temperature range of -40°C to +125°C.

Feature Summary

• High precision with 0.05% maximum initial accuracy and low temperature drift for stable reference performance.
• Supports bidirectional current flow with ±10 mA sourcing and sinking capability and low dropout voltage.
• Includes a dedicated noise reduction pin to minimize output noise when connected to ground via a capacitor.

Applications

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

Procurement Notes

Verify the specific ordering suffix VS1R-S corresponds to the MSOP-8 package and tape-and-reel transport media as defined in the manufacturer's order information table. Confirm that the required output voltage matches the fixed 1.25 V specification for this part number. Ensure design compliance with the recommended operating conditions regarding input voltage limits and thermal management constraints.

Selection Notes

Select this component for applications requiring a stable, low-noise reference voltage with high initial accuracy. The wide input voltage range allows flexibility in power supply design. Consider the thermal resistance characteristics of the MSOP-8 package for heat dissipation calculations. Verify that the required output current does not exceed the ±10 mA limit for optimal regulation performance.
