ADR363AUJZ-REEL7

Overview

The ADR363AUJZ-REEL7 is a micropower, low dropout voltage reference providing a nominal 3.000 V output in a compact TSOT-23-5 package. It features an initial accuracy of ±6 mV and a temperature coefficient of 25 ppm/°C across the −40°C to +125°C range. The device operates with a maximum quiescent current of 190 µA and supports sourcing up to 5 mA while sinking up to 1 mA. It requires no external capacitors for stability.

Feature Summary

• Proprietary temperature drift curvature correction techniques achieve low temperature drift within a compact TSOT package.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Band gap architecture references the ideal zero temperature coefficient voltage to the output rather than ground, attenuating noise on the ground line.

Applications

• Battery-powered instruments
• Portable medical instruments
• Data acquisition systems
• Industrial process controls

Procurement Notes

Verify the specific grade suffix (A) against the datasheet Table 1 to confirm the 25 ppm/°C temperature coefficient and ±6 mV accuracy specifications. Ensure the ordering suffix matches the reel packaging format required for automated assembly processes.

Selection Notes

Select this component when a stable 3.000 V reference is needed with minimal power consumption. The A grade offers higher temperature drift compared to the B grade but maintains the same low quiescent current profile suitable for battery-operated designs.

Part Context
