TPR70A0-SO1R

Overview

The TPR70A0-SO1R is a fixed-output series voltage reference IC manufactured by 3PEAK. It provides a stable 3V output with an accuracy of ±0.05% and a temperature coefficient of 6ppm/°C. The device operates within a supply voltage range of 3V to 15V, drawing a typical supply current of 1mA. It supports a maximum output current of 10mA and exhibits low noise of 3µVp-p in the 0.1Hz to 10Hz band. Designed for surface mount installation, it is housed in an 8-SOP package and functions reliably across an operating temperature range of -40°C to 125°C.

Feature Summary

• Delivers high-precision voltage regulation with ±0.05% initial accuracy
• Maintains stability through a low temperature coefficient of 6ppm/°C
• Features low-noise performance suitable for sensitive analog circuits
• Supports bidirectional current flow with ±10mA capability

Applications

• Precision data acquisition systems requiring stable reference voltages
• Analog-to-digital converter (ADC) reference inputs
• Sensor signal conditioning circuits
• Battery-powered instrumentation with strict power constraints

Procurement Notes

Verify the specific suffix SO1R corresponds to the 8-SOP surface-mount package configuration. Confirm that the 6ppm/°C temperature coefficient meets your thermal design requirements. Ensure the 3V fixed output aligns with your system's reference needs. Check RoHS3 compliance status if required by your manufacturing standards. Validate the 1mA supply current against your total power budget constraints.

Selection Notes

Select this component when a fixed 3V reference is required with high precision and low drift. The 6ppm/°C coefficient offers better thermal stability than standard references. The 10mA output current allows direct driving of moderate loads without external buffering. Consider the 8-SOP package for space-constrained PCB layouts. Evaluate the 3µVp-p noise specification for applications sensitive to low-frequency interference.
