TPR3312-QF11R-S

Overview

The TPR3312-QF11R-S is a fixed-output voltage reference IC from the 3PEAK TPR33 series, providing a stable 1.25 V output. It features high initial accuracy with a maximum tolerance of ±0.15% and a low temperature coefficient of 30 ppm/°C over an extended operating temperature range of −40°C to +125°C. The device operates within a supply voltage range of 2.1 V to 5.5 V, drawing a quiescent current of 180 µA. It exhibits low output noise of 25 µVpp (0.1 Hz to 10 Hz) and is stable with capacitive loads ranging from 0.1 µF to 10 µF.

Feature Summary

• Guaranteed temperature stability across the full industrial operating range
• High initial accuracy with minimal long-term drift
• Low noise performance suitable for precision analog circuits
• Capacitive load stability without requiring external compensation

Applications

• Precision instrumentation systems
• Industrial control applications
• Power supply monitoring circuits

Procurement Notes

Verify the specific package type against the datasheet, as the QFN-8 variant was removed in later revisions. Confirm the ordering suffix matches the required tape and reel quantity. Ensure the component meets RoHS compatibility standards for your assembly process.

Selection Notes

Select this part when a 1.25 V reference is required with tight accuracy constraints. Compare noise specifications against other TPR33 variants if lower noise is needed. Verify that the input voltage remains above the minimum dropout requirement for the expected load current.

Part Context

This component belongs to the TPR33 family of voltage references manufactured by 3PEAK. The family includes various output voltages such as 2.048 V, 2.5 V, and 3.3 V. While the datasheet primarily details SOT23G-3 packages, distributors list this specific model in an 8-QFN configuration.

Replacement Considerations

TPR3312-S3TR is the direct equivalent in the standard SOT23G-3 package.
