TPR5040-VS1R-S

Overview

The TPR5040-VS1R-S is a fixed-output voltage reference from the TPR50 series, providing a nominal output of 4.096 V in an MSOP8 package. It operates with an input voltage range of 3 V to 15 V and supports bidirectional current sourcing and sinking up to ±10 mA. The device features high initial accuracy of ±0.05% and low temperature coefficients ranging from 1 ppm/°C to 2.5 ppm/°C across specified ranges. Quiescent current is typically 1 mA, with a maximum dropout voltage of 400 mV at full load.

Feature Summary

• High precision with 0.05% initial accuracy and low temperature drift for stable reference performance
• Bidirectional output capability supporting both current sourcing and sinking of ±10 mA
• Integrated noise reduction pin allows external filtering to minimize output noise voltage
• Low dropout voltage design enables efficient operation across wide input voltage ranges

Applications

• Battery test equipment requiring precise voltage references
• Industrial control systems demanding high-resolution signal processing
• Precision instrumentation and measurement devices
• Medical equipment utilizing accurate analog front-ends

Procurement Notes

Verify the specific ordering suffix VS1R-S corresponds to the MSOP8 package variant when sourcing. Confirm RoHS compliance and halogen-free status as defined by the manufacturer's green product standards. Ensure the supply chain documentation matches the MSL3 classification for moisture sensitivity handling during assembly processes.

Selection Notes

Select this component for applications requiring a 4.096 V reference with tight tolerance specifications. The MSOP8 package suits designs with limited board space compared to larger footprints. Consider the NR pin for noise-sensitive circuits and verify thermal dissipation requirements based on the junction-to-ambient resistance values provided in the datasheet.

Part Context

This part belongs to the TPR50 series of low-noise, low-drift precision voltage references manufactured by 3PEAK. The series offers multiple fixed output voltages including 1.25 V, 2.5 V, and 5 V options. The TPR5040 specifically targets applications needing 4.096 V stability with high accuracy and low temperature coefficient characteristics.

Replacement Considerations
