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.


· Minimum Guaranteed Output Current: 1A · Dropout Voltage at IOUT=1A: 280mV Typ. (Except 1.2V and 1.8V Versions) · Output Accuracy: ± 1% · Low Ground Current · Internal Current Limit and Thermal Protection · Reversed-battery and Reversed-lead Insertion Protection · Fast Transient Response
