AZ39150 Datasheet | BCD Semiconductor

Description The AZ39150 is low dropout three-terminal regulator with a typical dropout of 375m V at 1.5A output current. The AZ39150 provides current limit and thermal shutdown. On-chip thermal shutdown provides protection against any bination of high current and ambient temperature that would create excessive junction temperatures. 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.
