ISL21010CFH315Z-T7A

Overview

The ISL21010CFH315Z-T7A is a precision, low dropout micropower bandgap voltage reference IC manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 1.5V with a tight tolerance of ±0.2%. The device operates from a single supply voltage ranging from 2.2V to 5.5V and delivers an output current of up to 25 mA. It features a maximum quiescent current of 100 µA and is housed in a compact SOT-23-3 package. The component is rated for operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• Precision bandgap architecture ensures stable voltage regulation under varying load conditions
• Low dropout design enables efficient operation with minimal input-to-output voltage differential
• Micropower consumption supports battery-powered applications requiring extended operational life
• Compact surface-mount packaging facilitates integration into space-constrained circuit designs

Applications

• Portable electronic devices requiring precise voltage regulation

Procurement Notes

Verify the specific suffix Z-T7A indicates tape and reel packaging when ordering. Confirm the 1.5V output variant matches system requirements. Check for RoHS compliance markings on official documentation. Ensure compatibility with SOT-23-3 footprint during PCB layout. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when a fixed 1.5V reference is required with high accuracy. Consider the ±0.2% tolerance for precision analog circuits. Evaluate the 100 µA quiescent current against power budget constraints. Verify that the SOT-23-3 package fits within available board space. Ensure input voltage remains within the 2.2V to 5.5V operating range.

Part Context

This part belongs to the ISL21010 series of micropower voltage references. The series offers various fixed output voltages including 1.5V, 2.5V, 3.3V, and 4.096V. All variants share similar electrical characteristics and packaging options. The series is designed for applications demanding low noise and high stability in small form factors.

Replacement Considerations

Direct substitutes include other ISL21010 variants with different output voltages if voltage adjustment is acceptable. Cross-reference with Intersil branded parts as Renesas acquired Intersil. Verify pinout compatibility before substitution. Check thermal performance similarities for identical mounting conditions.
