A Product Line of Diodes Incorporated AZ2940 1A ULTRA LOW DROPOUT LINEAR REGULATOR 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 shutdown. On-chip thermal shutdown provides protection against any combination of high current and ambient temperature that would create excessive junction temperatures. The AZ2940 has 1.2V, 1.8V, 2.5V, 3.3V and 5.0V versions. The AZ2940 series is ava.
