Overview
The ZXRE1004DRSTOB is a discontinued 1.22V bandgap shunt voltage reference manufactured by Diodes Incorporated. It operates within an 8µA to 20mA current range with a typical temperature coefficient of 20ppm/°C and a maximum of 75ppm/°C. The device provides ±1% initial accuracy, unconditionally stable performance under capacitive loads, and low wideband noise of 60µVrms (10Hz to 10kHz). It is housed in a SOT-23 surface-mount package.
Feature Summary
- Ultra-low power consumption with a typical knee current of 4µA
- High stability maintained across varying capacitive loads
- Pin-for-pin compatible alternative to legacy REF1004 and LT1004 references
Applications
- Battery powered equipment
- Precision power supplies
- Portable instrumentations
- Data acquisition systems
- A/D and D/A converters
Procurement Notes
This component is officially obsolete and not recommended for new designs. Verify availability through secondary market channels or authorized distributors holding remaining stock. Confirm the specific suffix matches the required tolerance and package variant before procurement, as ordering codes dictate exact electrical tolerances.
Selection Notes
Select this part only if utilizing existing legacy designs requiring a 1.22V reference. For new projects, consider modern equivalents from the same family or competitors offering active status. Ensure the design accommodates the specified operating current range and thermal requirements for the SOT-23 package.
Part Context
The ZXRE1004 series serves as a micro-power voltage reference designed for portable applications. It replaces older industry standards like the LM185 and LM385 while offering improved space efficiency via the SOT-23 footprint. The product line includes various tolerance grades ranging from 0.5% to 3%.
Replacement Considerations
Diodes Incorporated recommends using the ZXRE125 as the replacement for this obsolete part.
