TPR5050-VS1R-S

Overview

The TPR5050-VS1R-S is a fixed-output voltage reference from the TPR50 series, manufactured by 3PEAK. It provides a nominal output voltage of 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 both sourcing and sinking currents up to ±10 mA. It features a low dropout voltage and a typical temperature coefficient of 2.5 ppm/°C across the -40°C to +125°C operating range. Packaged in an 8-MSOP (0.118" width) surface-mount format, it includes a noise reduction pin for filtering.

Feature Summary

• High precision with 0.05% maximum initial accuracy and low temperature drift
• Bidirectional current capability supporting both sinking and sourcing of ±10 mA
• Integrated noise reduction pin allows for additional output filtering via external capacitor

Applications

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

Procurement Notes

Verify the specific package variant matches the design requirement, as the TPR50 family includes SOP8 and MSOP8 options. Confirm that the 5 V output voltage aligns with system reference needs. Ensure the PCB layout adheres to thermal guidelines, particularly regarding the junction-to-ambient resistance for the MSOP8 package. Check moisture sensitivity level (MSL 3) requirements for storage and reflow soldering processes.

Selection Notes

Select this component when a stable 5 V reference is required with high initial accuracy and low temperature drift. The bidirectional ±10 mA output current makes it suitable for driving ADCs or DACs directly. Consider the MSOP8 package for space-constrained designs. Verify that the input voltage remains within the 3 V to 15 V range under all operating conditions to ensure proper regulation and low dropout performance.

Part Context

The TPR5050-VS1R-S belongs to the TPR50 series of low-noise, low-drift precision voltage references. This series offers multiple fixed output voltages ranging from 1.25 V to 5 V. The TPR5050 specifically denotes the 5 V output variant. The 'VS1R-S' suffix indicates the MSOP8 package type and tape-and-reel packaging configuration.

Replacement Considerations

TPR5050-SO1R-S is the SOP8 package equivalent within the same series.
