TPR5030-SO1R

Overview

The TPR5030-SO1R is a fixed-output series voltage reference IC manufactured by 3PEAK, providing a nominal output of 3 V. It operates within 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 with a maximum tolerance of ±0.05% and low temperature drift, characterized by a typical coefficient of 2 ppm/°C from −40°C to 105°C and a maximum of 6 ppm/°C across the full −40°C to 125°C operating range. Quiescent current is typically 1 mA, and it exhibits low noise performance of 3 μVpp/V in the 0.1 Hz to 10 Hz bandwidth.

Feature Summary

• High precision with 0.05% maximum initial accuracy and low temperature drift for stable reference performance
• Bidirectional output capability supporting both sinking and sourcing currents up to ±10 mA
• Integrated noise reduction pin allows external filtering to minimize output noise levels

Applications

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

Procurement Notes

Verify the specific package type SOP8 and output voltage configuration against project requirements. Confirm RoHS compliance and MSL level 3 handling precautions during assembly. Ensure input voltage remains within the specified 3 V to 15 V range to maintain optimal regulation and thermal performance.

Selection Notes

Select this component for applications requiring high-resolution data acquisition where stable reference voltage is critical. Consider the ±10 mA output drive capability for direct interfacing with ADCs or DACs without additional buffering. Evaluate thermal dissipation based on the junction-to-ambient resistance if operating at higher ambient temperatures.

Part Context

This part belongs to the TPR50 series of low-noise, low-drift precision voltage references. The series offers multiple fixed output voltages including 1.25 V, 2.048 V, 2.5 V, 3 V, 3.3 V, 4.096 V, 4.5 V, and 5 V. It is available in SOP8 and MSOP8 packages, designed for systems demanding high accuracy and excellent temperature stability.

Replacement Considerations

Compatible alternatives within the same family include TPR5025-SO1R (2.5 V) and TPR5033-SO1R (3.3 V). For different package options, consider TPR5030-VS1R-S which provides the same 3 V output in an MSOP8 package.
