General Description
The AZ39150 is low dropout three-terminal regulator
with a typical dropout of 375mV at 1.5A output cur-
rent.
The AZ39150 provides current limit and thermal shut-
down. On-chip thermal shutdown provides protection
against any combination of high current and ambient
temperature that would create excessive junction tem-
peratures.
The AZ39150 is available for 3.3V, 5.0V and 12V ver-
sions now. It is available in the industry standard TO-
220-3, TO-263-3, TO-252-2(1), TO-252-2(2), TO-
252-2(3) and TO-252-2(4) power packages.
