Data Sheet

1A ULTRA LOW DROPOUT LINEAR REGULATOR

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 (1) power packages.
