Procurement Notes

Verify the specific suffix K2ZT2G against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with required input/output voltage ranges and load currents. Check RoHS compliance status and operating temperature ratings (-40°C to +85°C) for your application environment. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this model when a fixed 4.0V output is required from a single-cell or multi-cell battery source. Consider the 300mA output capability for moderate load applications. Evaluate the SC-74A package size against PCB layout constraints. Compare with other S-8352 variants if different output voltages or higher current capacities are needed. Ensure input voltage stays within the 0.9V to 10V range for proper regulation.

Part Context

This component belongs to the S-8352 series of step-up switching regulators by ABLIC Inc.
