TPR3312-S3TR-S

Overview

The TPR3312-S3TR-S is a fixed-output voltage reference IC from the 3PEAK TPR33 series, providing a precise 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 across the operating range. The device operates on a supply voltage between 2.1 V and 5.5 V, drawing a quiescent current of 180 μA. It delivers an output noise of 25 μVpp (0.1 Hz to 10 Hz) and supports capacitive loads from 0.1 μF to 10 μF. Packaged in SOT23G-3, it functions within a temperature range of −40°C to 125°C.

Feature Summary

• Guaranteed high initial accuracy and low temperature drift for stable reference performance
• Low power consumption with minimal quiescent current draw
• Capable of driving capacitive loads without stability issues
• Extended industrial temperature range operation

Applications

• Power supply monitoring and regulation circuits
• Precision instrumentation systems
• Industrial control equipment

Procurement Notes

Verify the specific suffix 'S' against official documentation to confirm package or tape-and-reel specifications. Ensure the ordering code matches the required SOT23G-3 form factor. Confirm RoHS compliance and halogen-free status as defined by the manufacturer's green product standards before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1.25 V reference is required with tight initial accuracy and low thermal drift. It is suitable for single-supply applications requiring low noise and minimal power consumption. Verify that the load capacitance remains within the specified 0.1 μF to 10 μF range to ensure circuit stability.

Part Context

This part belongs to the TPR33 family of voltage references manufactured by 3PEAK. The family includes variants with different fixed output voltages such as 2.048 V, 2.5 V, 3 V, 3.3 V, and 4.096 V. All members share similar electrical characteristics, including low quiescent current and high precision, but differ in their nominal output voltage levels.

Replacement Considerations

Other members of the TPR33 family, such as TPR3325-S3TR or TPR3333-S3TR, offer alternative fixed voltages with identical packaging and electrical profiles. Cross-reference pinouts and thermal characteristics when substituting with other voltage reference ICs from different manufacturers.
