REF191TRZ-EP

Overview

The REF191TRZ-EP is a precision micropower, low dropout voltage reference from the Enhanced Product series. It provides a fixed output of 2.050 V with an initial accuracy of ±2 mV and a maximum temperature coefficient of 5 ppm/°C. The device operates over a military temperature range of −55°C to +125°C and draws a maximum supply current of 50 µA in normal mode, reducing to 15 µA in sleep mode. It features short-circuit protection and supports loads up to 30 mA.

Feature Summary

Supports defense and aerospace applications through AQEC standard compliance
Utilizes proprietary temperature drift curvature correction and laser trimming for high stability
Includes a dedicated sleep pin for significant power reduction via TTL or CMOS logic levels

Applications

Portable instruments
ADCs and DACs
Smart sensors
Solar powered applications
Loop current powered instruments

Procurement Notes

Verify that the specific order includes the EP suffix to ensure receipt of the Enhanced Product variant. Confirm that the component meets the required AQEC standard for defense and aerospace usage. Check for controlled manufacturing baseline requirements and available qualification data before finalizing procurement decisions.

Selection Notes

Select this component when military-grade temperature operation between −55°C and +125°C is mandatory. Choose this part if the design requires a fixed 2.050 V reference with tight initial accuracy and low quiescent current consumption. Ensure the application benefits from the included sleep mode functionality for extended battery life in portable systems.
