Overview
The ZRB500F02TA is a precision micropower voltage reference IC manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to provide a stable 5.0V output with an initial accuracy of ±2%. The device operates within a recommended current range of 50µA to 15mA and features a typical temperature coefficient of 50ppm/°C. It is housed in a surface-mount SOT-23 package and supports operation between -40°C and +85°C.
Feature Summary
- Bandgap circuit design provides stable voltage without requiring external capacitors
- Capable of withstanding transient effects and currents up to 200mA due to rugged design
- Superior switching capability allows the device to reach stable operating conditions quickly
Applications
- Battery powered and portable equipment
- Metering and measurement systems
- Instrumentation
- Test equipment
- Data acquisition systems
Procurement Notes
Verify that the ordering suffix F02 corresponds to the specific ±2% tolerance required for your application, as other suffixes indicate different accuracies. Confirm the SOT-23 package type matches your PCB footprint. Ensure the component meets RoHS3 compliance standards if mandated by your project specifications.
Selection Notes
Select this component when a fixed 5V reference is needed in space-constrained designs. It is suitable for low-power applications due to its micropower characteristics. Consider the ±2% tolerance and 50ppm/°C temperature coefficient against your system's precision requirements before finalizing the design.
