ISL21010DFH312Z-T7A

Overview

The ISL21010DFH312Z-T7A is a precision micropower bandgap voltage reference in a space-saving SOT-23 package. It provides a fixed 1.25V output with ±0.2% initial accuracy and operates from a single supply ranging from 2.2V to 5.5V. The device delivers up to 25mA of output current sourcing capability with a low dropout voltage of 150mV. It features a typical supply current of 48μA, an output noise of 58μV P-P (0.1Hz to 10Hz), and a temperature coefficient of 50ppm/°C. Operating temperatures range from -40°C to +125°C.

Feature Summary

Micropower consumption suitable for battery-powered applications
High precision with ±0.2% initial accuracy
Low dropout voltage operation
Compact SOT-23 surface-mount packaging

Applications

Battery management and monitoring systems
Portable instrumentation
Consumer and medical electronics
Power regulation circuits
Control loops and compensation networks

Procurement Notes

Verify the specific suffix Z-T7A indicates tape-and-reel packaging configuration. Confirm the component status as obsolete or active through official Renesas channels before procurement planning. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Check for any recent Product Change Notifications regarding labeling or manufacturing site updates.

Selection Notes

Select this component when a stable 1.25V reference is required with minimal quiescent current draw. The wide operating temperature range supports industrial environments. Verify input voltage constraints against the 2.2V minimum requirement for the 1.25V output variant. Consider the 25mA source capability for driving downstream loads without external buffering.
