Sep. 2005 Rev. 1. 4
BCD Semiconductor Manufacturing Limited
General Description
The AZ2940 is a low dropout three-terminal regulator
with a typical dropout of 280mV at 1A output current.
The AZ2940 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 AZ2940 has 2.5V, 3.3V and 5.0V versions.
The AZ2940 is available in the industry standard TO-
220-3, TO-263-3 and TO-252-2 power packages.
