Procurement Notes

Verify the specific ordering suffix and package type against official datasheets to ensure compatibility with your PCB footprint. Confirm that the component status aligns with your production timeline, as some variants may be marked as not for new designs. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure thermal requirements are met given the SOT-89-5 package constraints.

Selection Notes

Select this component when a fixed 2.5V output is required with high efficiency and low standby current. Consider the 400mA output capability and 250mV dropout voltage for systems operating near the lower end of the input range. Verify that the integrated voltage detector meets system monitoring needs without requiring additional discrete components.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. It is specifically engineered for applications requiring both regulated power and voltage monitoring in a compact form factor. The SOT-89-5 package provides a balance of thermal performance and space efficiency for mobile and handheld devices.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series or family if availability is an issue. Ensure replacement parts match the 2.5V output, 400mA current rating, and SOT-89-5 package. Verify that any substitute maintains similar dropout voltage and quiescent current specifications.
