Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct pinout and functional configuration. Confirm that the SOT-89-5 package variant matches your PCB footprint requirements. Check for RoHS compliance status in the latest datasheet revision. Ensure operating conditions remain within the specified -40°C to +85°C temperature range for guaranteed performance. Validate input voltage limits do not exceed the absolute maximum ratings defined in the manufacturer's specifications.

Selection Notes

Select this component when a combined voltage regulation and detection function is required in a minimal footprint. The 1.5 V fixed output suits logic circuits or sensors operating at this specific rail. Consider the 400 mA output current capacity against peak load demands. The low quiescent current makes it suitable for energy-sensitive designs. Ensure the input voltage stays above the minimum requirement while respecting the maximum limit to prevent damage.
