TPR3530-S3TR

Overview

The TPR3530-S3TR is a fixed-output voltage reference from the 3PEAK TPR35 family, providing a nominal output of 3 V. It operates within a supply voltage range of 2.1 V to 5.5 V and delivers a quiescent current of 210 μA. The device features high initial accuracy with a maximum deviation of ±0.2% and low temperature drift of 30 ppm/°C over the -40°C to 85°C range. It supports capacitive loads between 0.1 μF and 10 μF and includes short-circuit protection.

Feature Summary

• Guaranteed temperature stability across the full operating range
• High initial accuracy with low temperature coefficient
• Low output noise performance
• Stable operation with capacitive loads

Applications

• Power systems
• Instrumentation
• Industrial equipment

Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm RoHS compliance and halogen-free status as defined by the manufacturer's green product standards. Ensure the input voltage remains within the recommended operating conditions to maintain specified line regulation and thermal performance.

Selection Notes

Select this component for applications requiring a precise 3 V reference with low power consumption. Consider the 30 ppm/°C temperature coefficient for environments with moderate thermal variations. Verify that the load capacitance falls within the stable range of 0.1 μF to 10 μF to prevent oscillation.

Part Context

This part belongs to the TPR35 series of voltage references manufactured 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. All variants share similar electrical characteristics and are housed in the SOT23G-3 package.

Replacement Considerations

Other members of the TPR35 family, such as TPR3525-S3TR or TPR3533-S3TR, offer different fixed output voltages but share identical pinouts and packaging. Direct substitution requires verifying that the alternative voltage level meets the circuit design requirements.
