Procurement Notes

Verify the specific suffix 'ETI+T' against the manufacturer's current datasheet to confirm pinout and thermal pad specifications. Confirm RoHS compliance status as indicated by the '+' suffix. Check for end-of-life notifications or obsolescence warnings directly from Analog Devices, as availability may be limited for legacy PMIC components.

Selection Notes

Select this component when designing DDR memory power rails requiring fast transient response. Ensure the input supply voltage remains within the 2V to 28V range. Verify that the required output voltage falls within the 0.7V to 5.5V adjustable window or matches the fixed 1.8V/2.5V options. Confirm thermal requirements fit the 28-TQFN package constraints.

Part Context
