Overview
The UPC1093T-1-E2-AZ is a shunt precision voltage reference manufactured by Renesas Electronics. It operates within an input voltage range of 2.495 V to 36 V and features an initial accuracy of 2%. The device has a maximum series VREF input voltage of 2.55 V and supports a maximum shunt current of 100 mA. It exhibits a temperature coefficient of 100 ppm/°C and functions between -20°C and +85°C. The component is housed in an SMD/SMT SOT-89-3 package.
Feature Summary
- Provides stable shunt regulation for precision voltage referencing applications
- Operates with high input voltage tolerance up to 36 V
- Maintains specified performance across industrial temperature ranges
Applications
- Precision measurement systems requiring stable reference voltages
- Data acquisition circuits needing accurate voltage benchmarks
- Power management ICs utilizing shunt regulation principles
Procurement Notes
Verify the specific suffix E2-AZ against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with SOT-89-3 footprint requirements during PCB design. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference part numbers with authorized distributors to avoid obsolete or counterfeit components.
Selection Notes
Select this component when a shunt-type reference is required rather than a series regulator. Consider the 2% initial accuracy and 100 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 100 mA maximum shunt current capability against circuit load requirements. Verify that the SOT-89-3 package fits the available board space and thermal dissipation constraints.
Part Context
This device belongs to the UPC1093T series of voltage references from Renesas Electronics. It serves as a fundamental building block for power management integrated circuits (PMIC). The shunt architecture distinguishes it from series regulators, offering a specific solution for maintaining reference potentials in parallel configurations within electronic systems.
Replacement Considerations
Consult official substitution guides for compatible shunt voltage references. Verify pinout compatibility and electrical parameter alignment before replacing.
