ZXRE250ASA-7

Overview

The ZXRE250ASA-7 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of VREF to 36V and supports a sink current capability from 0.065mA to 100mA. The device features an initial reference voltage tolerance of ±1.0% at +25°C, with a typical minimum cathode current for regulation of 40µA. It provides excellent temperature stability across an operating ambient temperature range of -40°C to +125°C.

Feature Summary

Adjustable output voltage set between 2.5V and 36V using external divider resistors
Very low minimum cathode current requirement for regulation
Low dynamic output impedance for stable performance
Totally lead-free and fully RoHS compliant

Applications

Optocoupler linearisers
Shunt regulators
Improved Zener diode replacement
Variable reference circuits

Procurement Notes

Verify component authenticity through authorized channels. Confirm the specific A-grade tolerance matches design requirements. Check datasheet revisions for updates. Ensure compliance with environmental directives. Validate package dimensions against PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when low quiescent current is critical. Use it where standard zener diodes lack sufficient accuracy or temperature stability. Consider the SOT-23 package for space-constrained designs. Evaluate the 1% tolerance grade against circuit sensitivity requirements. Verify compatibility with available external resistor values for target voltage setting.

Part Context

This part belongs to the ZXRE25x series of adjustable shunt regulators. It serves as a functional alternative to industry-standard devices like the TL431 but offers lower minimum cathode current. The series includes variants with different pinouts and tolerances. It falls under the PMIC category for power management applications requiring precise voltage referencing.
