TPR3320-S3TR-S

Overview

The TPR3320-S3TR is a fixed-output voltage reference from the 3PEAK TPR33 family, delivering a nominal output of 2.048 V in an SOT23G-3 surface-mount package. It features high initial accuracy with a maximum deviation of ±0.15% and a low temperature coefficient of 30 ppm/°C across the extended operating range of −40°C to +125°C. The device operates with a supply voltage between 2.1 V and 5.5 V, drawing a quiescent current of 180 μA. It supports capacitive loads from 0.1 μF to 10 μF and includes short-circuit protection.

Feature Summary

• Guaranteed temperature stability over an extended industrial range from −40°C to +125°C
• High precision with initial accuracy within ±0.15% and low temperature drift
• Stable operation with capacitive loads ranging from 0.1 μF to 10 μF
• Integrated short-circuit protection for sourcing and sinking currents

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel configuration for automated assembly processes. Confirm compliance with RoHS standards and halogen-free requirements as defined by the manufacturer's green product designation. Ensure input voltage constraints are respected during system design to maintain specified line regulation performance.

Selection Notes

Select this component when a stable 2.048 V reference is required in space-constrained designs utilizing the SOT23G-3 footprint. Consider the 180 μA quiescent current for battery-powered applications where power efficiency is critical. Evaluate the 30 ppm/°C temperature coefficient against system accuracy requirements across the full −40°C to +125°C operational window.
