TPR5020-VS1R-S

Overview

The TPR5020-VS1R-S is a high-precision series voltage reference from the TPR50 family, manufactured by 3PEAK. It provides a fixed output voltage of 2.048 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. Key electrical characteristics include a typical temperature coefficient of 2 ppm/°C from −40°C to 105°C and low noise performance of 3 μVpp/V in the 0.1 Hz to 10 Hz band. It is housed in an 8-pin MSOP package and functions reliably 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.
• Features a dedicated Noise Reduction (NR) pin allowing external filtering to minimize output noise levels.

Applications

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

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 design implementation accounts for the specified MSL level and thermal resistance parameters during layout. Validate that the required output voltage matches the fixed 2.048 V specification for the TPR5020 model.

Selection Notes

Select this component for applications requiring high-resolution analog-to-digital conversion references where stability over temperature is critical. The wide input voltage range accommodates various supply rails, while the low quiescent current aids power efficiency. Consider the NR pin functionality if ultra-low noise is required beyond the inherent specifications. Ensure the MSOP8 package dimensions fit the target PCB footprint constraints.

Part Context

This part belongs to the TPR50 series, which includes multiple fixed output voltage options ranging from 1.25 V to 5 V. The series shares common architectural features such as low temperature drift and high initial accuracy. Other variants in the family include SOP8 packages and different output voltages like TPR5030 or TPR5050, offering flexibility for diverse system requirements while maintaining consistent performance characteristics.

Replacement Considerations

Direct substitutes within the same family include TPR5020-SO1R for the SOP8 package variant. Cross-family replacements require matching output voltage, accuracy, and package type. Verify thermal and electrical compatibility before substituting with components from other manufacturers.

FAQ

How does the NR pin function on the TPR5020-VS1R-S?

The NR pin allows for additional noise reduction. Connecting a capacitor of 10 nF or larger from the NR pin to ground minimizes the output noise level further than the inherent device noise.

What is the maximum load current capability?

The device supports both sourcing and sinking currents up to ±10 mA, making it suitable for driving moderate loads without significant voltage drop.
