ADR381ARTZ-REEL7

Overview

The ADR381ARTZ-REEL7 is a micropower, low dropout voltage reference providing a fixed 2.500 V output in a 3-lead SOT-23 package. It features an initial accuracy of ±6 mV (±0.24%) and a maximum temperature coefficient of 25 ppm/°C across the −40°C to +85°C range. The device operates with a supply voltage from 2.8 V to 18 V, drawing a maximum quiescent current of 120 μA while delivering up to 5 mA of load current.

Feature Summary

• Patented temperature drift curvature correction techniques minimize nonlinearity of the voltage change with temperature.
• Micropower architecture enables operation from supplies as low as 300 mV above the output voltage.
• Stable performance maintained without requiring an output capacitor for stability under any load condition.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging quantity and RoHS compliance status. Confirm that the component meets all electrical specifications required for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a stable 2.500 V reference is needed in a compact surface-mount footprint. Ensure the input supply voltage remains within the specified operating range and consider thermal dissipation if operating at high ambient temperatures or with large differential voltages.

Part Context

This part belongs to the ADR38x series of precision band gap voltage references manufactured by Analog Devices. It shares architectural similarities with the ADR380 but provides a distinct nominal output voltage optimized for standard logic and ADC reference applications requiring precise voltage levels.
