REF3225AMDBVREP

Overview

The REF3225AMDBVREP is a series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2.55 V to 5.5 V and draws a supply current of 120 µA. It features a temperature coefficient of 40 ppm/°C and supports a maximum load current of 10 mA. The component is housed in a SOT-23-6 surface-mount package and functions reliably across a junction temperature range of -55°C to +125°C.

Procurement Notes

Verify the specific suffix 'EP' against official documentation, as it may indicate an enhanced product or specific qualification level distinct from standard commercial variants. Confirm the exact manufacturer part number on the datasheet to ensure compatibility with design requirements. Check for obsolescence status, as similar models like the REF3225AMDBVREPG4 are marked as not recommended for new designs. Validate moisture sensitivity levels and reflow soldering profiles before procurement.

Selection Notes

Select this component when a compact SOT-23-6 footprint is required alongside moderate precision and low quiescent current. Compare the 40 ppm/°C temperature coefficient against stricter drift requirements; if lower drift is needed, consider the REF34xx series. Ensure the input voltage remains above 2.55 V for proper regulation. Evaluate the 10 mA output drive capability against load demands to prevent dropout conditions during peak operation.

Part Context

This device belongs to the REF32xx family of micropower voltage references designed for battery-operated systems. It utilizes bandgap technology to maintain stability over temperature variations. The SOT-23-6 package allows for space-constrained PCB layouts. It serves as a critical reference element in analog-to-digital converter circuits and sensor signal conditioning stages where noise and drift must be minimized.

Replacement Considerations

Publicly confirmed substitute part numbers include ADR3425ARJZ-R7.
