Features:
The OM8504 is an ultra low dropout adjustable linear regu-
lator designed specifically for hi-rel applications. Housed
in either a 5 pin through hole or 8 lead surface mount
package these regulators provide high reliability in mili-
tary/defense applications. The ultra low dropout voltage of
0.4V @ 3A makes the part particularly useful for applica-
tions requiring low noise and higher efficiency.
