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. (Detailed information please
refer to page 2 &3)
