PRODUCT DESCRIPTION  
The SPX2940 is a low powered positive voltage regulator. The SPX2940 offers 1A output current with dropout voltage of only 0.5V  
and over temperature dropout is up to 1V. The quiescent current is 30mA at differential output of 5V and output current of 1A. The  
higher quiescent current can be exist when the device is in dropout mode (VIN – VOUT < 3V).  
Other key additional features of this device includes higher output current, positive transient protection up to 60V (load dump), and  
ability to survive an unregulated input voltage transient of -20V below ground (reverse battery). The regulator will automatically shut  
down to protect both the internal circuits and the load. This device also features short circuit and thermal overload protection.  
The SPX2940 is offered in a 3-pin TO-220 and TO-263 package compatible with other 5V regulators. This device offers a variety of  
output voltages: 3.3V, 5V and 12V. SPX2940 is direct replacement to LM2940.
