Preliminary Datasheet
1.5A ULTRA LOW DROPOUT LINEAR REGULATOR
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 and 5.0V versions
now. It is available in the industry standard TO-220-3
and TO-263-3 power packages.
