ZXRE4041CFTA

Overview

The ZXRE4041CFTA is a micropower shunt voltage reference providing a fixed output of 1.225V with 0.5% initial accuracy. It operates within a current range of 30µA to 12mA and features a typical temperature coefficient of 20ppm/°C across an operating temperature range of -40°C to +125°C. The device is housed in a compact SOT-23 surface-mount package, designed for space-constrained applications requiring high precision.

Feature Summary

Provides a precise 1.225V bandgap reference voltage with 0.5% tolerance
Operates efficiently at low currents starting from a 30µA knee current
Maintains excellent stability under capacitive loads without oscillation
Offers a direct pin-for-pin replacement for LM4041 references

Applications

Battery powered equipment
Precision power supplies
Portable instrumentation
Data acquisition systems
A/D and D/A converters

Procurement Notes

Verify the specific suffix 'C' confirms the 0.5% tolerance grade required for your design. Confirm that the SOT-23 footprint matches your PCB layout constraints. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain the guaranteed temperature coefficient performance.

Selection Notes

Select this component when a low-cost, space-saving alternative to the LM4041 is needed. It is suitable for designs requiring tight voltage accuracy (0.5%) and low quiescent current consumption. Consider its unconditionally stable nature for circuits driving significant capacitive loads directly.

Part Context

This part belongs to the ZXRE4041 series of micro-power voltage references manufactured by Diodes Incorporated. It utilizes a bandgap circuit topology to achieve high precision in a small outline SOT-23 package, targeting portable and battery-operated electronic devices where size and power efficiency are critical design factors.
