TPR5050-SO1R

Overview

The TPR5050-SO1R is a fixed-output voltage reference providing 5 V with ±0.05% initial accuracy and a typical temperature coefficient of 2.5 ppm/°C from −40°C to 125°C. It operates within a 3 V to 15 V input range, supports ±10 mA sourcing/sinking current, and features low dropout voltage (400 mV at ±10 mA). The device includes an NR pin for noise reduction, achieving 3 μVpp/V output noise (0.1 Hz to 10 Hz), and is housed in an SOP8 package.

Feature Summary

• High precision with 0.05% maximum initial accuracy and low temperature drift
• Supports bidirectional current flow with ±10 mA sourcing and sinking capability
• Integrated noise reduction pin allows further filtering via external capacitor
• Low dropout voltage ensures stable regulation across wide input ranges

Applications

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

Procurement Notes

Verify the specific suffix SO1R corresponds to the SOP8 package configuration. Confirm RoHS compliance and MSL rating during procurement. Ensure ordering matches the exact 5 V output variant within the TPR50 family. Validate thermal resistance parameters against system dissipation requirements before finalizing supply agreements.

Selection Notes

Select this component when high-resolution systems require a stable 5 V reference with minimal temperature drift. Consider the NR pin functionality if ultra-low noise performance is critical. Evaluate the ±10 mA current capability against load demands to ensure operation remains within the specified dropout voltage limits under varying line and 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 including 1.25 V, 2.5 V, and 5 V. All variants share similar electrical characteristics and are available in SOP8 and MSOP8 packages for various industrial and commercial applications.

Replacement Considerations

TPR5050-VS1R-S provides the same 5 V specification in an MSOP8 package.

FAQ

How does the NR pin function?

The NR pin allows for additional noise filtering. Connecting a 10-nF or larger capacitor from the NR pin to ground minimizes the output noise level.

What is the maximum output current capability?

The device supports both sourcing and sinking currents up to ±10 mA while maintaining specified accuracy and dropout voltage performance.
