ISL21007DFB825Z

Overview

The ISL21007DFB825Z is a precision, low dropout micropower bandgap voltage reference manufactured by Intersil (Renesas). It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.16%. The device features a temperature coefficient of 10 ppm/°C and operates within a supply voltage range up to 5.5 V. It is housed in an 8-SOIC package and supports a maximum shunt current of 5 mA. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with low initial accuracy error
• Features extremely low power consumption suitable for battery-operated systems
• Incorporates low noise characteristics for sensitive analog signal processing
• Utilizes FGA technology for enhanced stability and performance

Applications

• Portable instrumentation requiring low power consumption
• Data acquisition systems needing stable reference voltages
• Battery-powered measurement devices
• Industrial process control circuits

Procurement Notes

Verify the manufacturer origin, as Intersil products are now under Renesas Electronics. Confirm the specific suffix matches the required tolerance and packaging format. Check for RoHS compliance status and moisture sensitivity levels before integration. Ensure the source is an authorized distributor to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select this component when a fixed 2.5 V reference with ±0.16% accuracy is required in an 8-SOIC package. It is suitable for applications demanding low quiescent current and low noise. Compare against other ISL2100x series variants if different output voltages or tighter tolerances are needed. Ensure the operating temperature range meets the environmental requirements of the target system.

Part Context

This part belongs to the ISL2100x series of FGA™ voltage references, designed for high precision and low noise applications. Intersil was acquired by Renesas Electronics, which continues to support and manufacture these legacy analog components. The series is known for combining high accuracy with micropower operation, making it ideal for modern portable and industrial electronics.

Replacement Considerations

Direct substitutes include other parts from the ISL2100x family with matching 2.5 V output and SOIC-8 packaging. Verify pin compatibility and electrical specifications such as temperature coefficient and initial accuracy before substitution.
