LD2940

1A Ultra Low Dropout Voltage Regulator LD2940 Series 1A Ultra Low Dropout Voltage Regulator General Description The LD2940 is a low dropout three-terminal regulator with a typical dropout of 280mV at 1A output current. The LD2940 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 LD2940 has 1.2V, 1.8V, 2.5V, 3.3V and 5.0V versions. The LD2940 series is available in the industry standard TO-220, TO-263-3, DPAK(TO-252) and SOT-223 power packages.
