1.5A ULTRA LOW DROPOUT LINEAR REGULATOR AZ39150
General Description
The AZ39150 is low dropout three-terminal regulator
with a typical dropout of 375mV at 1.5A output current.
The AZ39150 provides current limit and thermal shutdown. On-chip thermal shutdown provides protection
against any combination of high current and ambient
temperature that would create excessive junction temperatures.
The AZ39150 is available for 3.3V, 5.0V and 12V versions now. It is available in the industry standard TO220-3, TO-263-3, TO-252-2(1), TO-252-2(2), TO252-2(3) and TO-252-2(4) power packages.
