Overview
The ISL21080CIH350Z-TK is a fixed voltage reference from the ISL21080 series, manufactured by Renesas Electronics. It provides a precise output of 3.5 V with an initial accuracy of ±0.2%. The device operates within a supply voltage range of 2 V to 5.5 V and delivers up to 7 mA of output current. It features a temperature coefficient of 50 ppm/°C, line regulation of 350 μV/V, and load regulation of 350 μV/mA. Designed for surface mount installation, it utilizes a compact SOT-23-3 package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides stable precision voltage reference with high initial accuracy
- Operates efficiently with low quiescent current consumption
- Compact three-pin surface-mount design for space-constrained applications
Applications
- Portable instrumentation requiring stable reference voltages
- Battery-powered measurement systems
- Data acquisition systems
Procurement Notes
Verify the specific suffix Z-TK indicates tape-and-reel packaging when ordering. Confirm the 3.5 V output variant matches the design requirement, as the ISL21080 series offers multiple fixed voltage options. Ensure the SOT-23-3 footprint aligns with the PCB layout specifications. Check for RoHS compliance status if required by project standards.
Selection Notes
Select this component when a fixed 3.5 V reference is needed with ±0.2% accuracy. Consider the 50 ppm/°C temperature coefficient for thermal stability requirements. The 7 mA output current supports moderate load demands without external buffering in many cases. Verify input voltage stays within the 2 V to 5.5 V operational window.
Part Context
The ISL21080 series represents Renesas' portfolio of low-power, precision voltage references. These devices are engineered for applications demanding high stability and low noise. The series includes various fixed output voltages and packages, catering to diverse industrial and consumer electronics needs while maintaining consistent performance characteristics.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the ISL21080 family or equivalent Renesas voltage references. Verify pinout compatibility and electrical parameter alignment before replacing.
