Hi all
I'm using the L5970AD to provide a 3.3V supply, however the undervoltage
lockout (UVLO) does not appear to operate when the input voltage drops
too low for normal regulation to occur; that is, the output voltage does
not shut down cleanly but droops at about 0.5V below the input voltage.
This is proving a major problem as the equipment is battery operated
some of the time. Does anyone have any info on what this device actually
does or how the UVLO actually operates.
Cheers
Brian
