TPR5033-VS1R-S

Overview

The TPR5033-VS1R-S is a fixed-output series voltage reference providing 3.3 V with ±0.05% initial accuracy and a typical temperature coefficient of 2 ppm/°C from −40°C to 105°C. It operates within a 3 V to 15 V input range, drawing 1 mA quiescent current. The device supports ±10 mA bidirectional output current and features low noise (3 μVpp/V). Packaged in MSOP8, it includes an NR pin for noise reduction and functions across a −40°C to 125°C temperature range.

Feature Summary

• High precision with 0.05% maximum initial accuracy
• Low temperature drift of 2.5 ppm/°C over the full operating range
• Bidirectional current capability supporting both sinking and sourcing up to ±10 mA
• Integrated noise reduction pin for enhanced signal integrity

Applications

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

Procurement Notes

Verify the specific package variant matches the design requirements, as the TPR50 family includes SOP8 and MSOP8 options. Confirm that the 3.3 V output aligns with system voltage needs. Ensure ESD protection protocols are followed during handling due to the sensitivity of precision analog components. Check RoHS compliance status if required by environmental regulations.

Selection Notes

Select this component when high stability and low drift are critical for ADC or DAC references. The MSOP8 package suits space-constrained designs compared to the larger SOP8 option. Consider the NR pin usage if ultra-low noise performance is necessary for sensitive measurement applications. Verify input voltage headroom meets the minimum dropout requirements under load conditions.

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 ranging from 1.25 V to 5 V. It is designed for high-resolution systems requiring stable reference sources. The MSOP8 package provides a compact footprint suitable for modern surface-mount assembly processes.

Replacement Considerations

Direct substitutes within the TPR50 family include other output voltage variants like TPR5030-VS1R-S or TPR5025-VS1R-S if voltage adjustment is feasible. Cross-brand replacements require matching accuracy, temperature coefficient, and package dimensions. Verify pinout compatibility and thermal characteristics before substitution.
