Overview
The ISL21080CIH315Z-T7A is a fixed voltage reference from the Renesas ISL21080 series, providing a 1.5V output in a compact SOT-23-3 package. It features an initial accuracy of ±0.2% and a temperature coefficient of 50 ppm/°C. The device operates with an input voltage range of 2V to 5.5V and delivers up to 7mA of output current. Line regulation is specified at 350 μV/V, while load regulation is 350 μV/mA. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Provides a stable 1.5V fixed reference voltage with high precision.
- Features low temperature drift for consistent performance across operating ranges.
- Designed for surface-mount integration in space-constrained applications.
Applications
- Precision analog-to-digital converter (ADC) reference sources
- Digital-to-analog converter (DAC) voltage references
- Battery-powered instrumentation requiring stable bias voltages
Procurement Notes
Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging details. Ensure the part number matches the exact voltage grade and tolerance required for your design. Cross-reference the manufacturer's latest datasheet for any updates on pinout or electrical characteristics before finalizing procurement.
Selection Notes
Select this component when a precise 1.5V reference is needed in a small footprint. Consider its ±0.2% initial accuracy and 50 ppm/°C temperature coefficient for applications demanding stability over temperature variations. Evaluate the 7mA drive capability against the load requirements of the connected circuitry.
Part Context
This part belongs to the ISL21080 family of micropower voltage references by Renesas Electronics. These devices are designed to offer high accuracy and low power consumption in a tiny SOT-23 package. The family includes various fixed voltage options, catering to diverse reference needs in portable and industrial electronics.
Replacement Considerations
Check for direct substitutes within the ISL21080 series offering different voltage outputs if 1.5V is not suitable. Verify compatibility with other manufacturers' 1.5V references in the SOT-23-3 package, ensuring pinout and electrical specifications align with the original design requirements.
