Overview
The ZXRE125DRSTZ is a micropower shunt voltage reference IC from Diodes Incorporated, providing a fixed 1.22V output with ±1% initial accuracy. It operates within a current range of 8µA to 20mA and features a typical temperature coefficient of 20ppm/°C. The device is housed in an SOT-23 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Bandgap circuit architecture designed for precision micropower applications
- Unconditionally stable operation with high tolerance for capacitive loads
- Low knee current of 4µA enabling extended battery life
- Green molding compound compliant with RoHS standards
Applications
- Battery powered equipment
- Precision power supplies
- Portable instrumentation
- Data acquisition systems
Procurement Notes
Verify the specific ordering suffix 'RSTZ' against the official datasheet, as standard variants listed include CFTA, DFTA, EFTA, and FFTA. Confirm availability status, as certain E-line variants are marked obsolete. Ensure the selected part matches the required tolerance grade and packaging specifications for your design.
Selection Notes
Select this component when space-saving SOT-23 packaging is required alongside precise voltage referencing. It serves as a pin-for-pin compatible replacement for ZRA124 and ZRA125 series references. Consider the 8µA minimum operating current requirement to ensure proper regulation during low-power states.
Part Context
This device belongs to the ZXRE125 series of bandgap voltage references manufactured by Diodes Incorporated. The series offers multiple tolerance grades (0.5%, 1%, 2%, 3%) in a compact surface-mount form factor. It is categorized under PMIC voltage references for general-purpose precision applications.
Replacement Considerations
The datasheet confirms pin-for-pin compatibility with the ZRA124 and ZRA125 series of voltage references. Verify that substitute components maintain the same 1.22V reference voltage and SOT-23 footprint requirements.
