TPR3525-S3TR

Overview

The TPR3525-S3TR is a fixed-output voltage reference IC from the 3PEAK TPR35 family, providing a nominal output of 2.5 V in an SOT23G-3 package. It operates within a supply voltage range of 2.1 V to 5.5 V and maintains high accuracy with an initial tolerance of ±0.2%. The device features low temperature drift of 30 ppm/°C over the industrial range (-40°C to 85°C) and 50 ppm/°C over the extended range (-40°C to 125°C). Key electrical characteristics include a quiescent current of 210 μA, output noise of 50 μVpp (0.1 Hz to 10 Hz), and stability with capacitive loads between 0.1 μF and 10 μF.

Feature Summary

• Guaranteed high initial accuracy of ±0.2% across the full operating temperature range.
• Low output noise performance of 50 μVpp measured between 0.1 Hz and 10 Hz.
• Operates stably with capacitive loads ranging from 0.1 μF to 10 μF without oscillation.

Applications

• Precision power supply regulation
• Data acquisition systems
• Industrial instrumentation

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity of 3,000 units. Confirm the package marking code R3C corresponds to the intended manufacturing batch. Ensure compliance with RoHS standards and halogen-free requirements as defined by the manufacturer for environmental specifications.

Selection Notes

Select this component when a stable 2.5 V reference is required with tight initial accuracy and low noise. Consider the SOT23G-3 package for space-constrained designs. Evaluate the 30 ppm/°C temperature coefficient against system thermal requirements. Verify that the 210 μA quiescent current aligns with power budget constraints.

Part Context

The TPR3525-S3TR belongs to the TPR35 series of voltage references manufactured by 3PEAK. This family offers multiple fixed output voltages including 1.25 V, 2.048 V, 3 V, 3.3 V, and 4.096 V. All variants share similar electrical characteristics and are housed in the compact SOT23G-3 package, designed for general-purpose precision applications.

Replacement Considerations

Direct substitutes within the same family include TPR3512-S3TR, TPR3520-S3TR, TPR3530-S3TR, TPR3533-S3TR, and TPR3540-S3TR, which differ only in output voltage.
