I have ADP2503-3.3 , fed from 3.5v. when put Enable in low the Vout is ~1.5volts, why not 0 volts ?
Can you share the schematics with us? (what else is around the ADP2503 besides the recommended cirrcuit of the datasheet?)
Also a scope plot showing Vin rising, Vout and EN ON/OFF would be great.
Retrieving data ...
