TPR3330-QF11R-S

Overview

The TPR3330-QF11R-S is a fixed-output voltage reference IC from the TPR33 series, manufactured by 3PEAK. It provides a nominal output voltage of 3.0 V with an initial accuracy of ±0.15% and a temperature coefficient of 30 ppm/°C. The device operates within a supply voltage range of 2.1 V to 5.5 V and draws a quiescent current of 180 µA. It features low output noise of 60 µVpp (0.1 Hz to 10 Hz) and supports capacitive loads between 0.1 µF and 10 µF. The component is rated for operation from −40°C to +125°C.

Feature Summary

• Guaranteed high initial accuracy and low temperature drift across the full operating temperature range
• Low power consumption with a quiescent current of 180 µA
• Capable of driving capacitive loads ranging from 0.1 µF to 10 µF without instability

Applications

• Power systems requiring stable reference voltages
• Industrial instrumentation and measurement devices
• Data acquisition systems

Procurement Notes

Verify that the specific suffix QF11R-S corresponds to the requested package variant, as the primary datasheet lists SOT23G-3 packaging for the TPR3330 family. Confirm RoHS compliance and lead times directly with authorized distributors or the manufacturer, as standard delivery periods may vary based on production schedules and regional availability constraints.

Selection Notes

Select this component when a precise 3.0 V reference is required with tight tolerance specifications. The low quiescent current makes it suitable for battery-powered applications. Ensure the load capacitance remains within the specified 0.1 µF to 10 µF range to maintain stability. Consider the thermal performance and package type relative to the available board space and heat dissipation requirements in the target design.

Part Context

This part belongs to the TPR33 series of precision voltage references designed by 3PEAK. The series offers multiple fixed output voltages including 1.25 V, 2.048 V, 2.5 V, 3 V, 3.3 V, and 4.096 V. These devices are engineered for applications demanding high stability and low noise, serving as critical components in analog signal chains and power management circuits.

Replacement Considerations

Direct substitutes include other members of the TPR33 family such as TPR3325-S3TR (2.5 V) or TPR3333-S3TR (3.3 V) if voltage adjustment is acceptable. Cross-brand replacements should match the 3.0 V output, ±0.15% accuracy, and SOT23G-3 package dimensions while verifying electrical compatibility.
