DESCRIPTION  
TheSPX2940isa1A, accuratevoltageregulatorswithalowdropoutvoltageof280mV(typical)  
at 1A. These regulators are specifically designed for low voltage applications that require a low  
dropoutvoltageandafasttransientresponse.Theyarefullyfaultprotectedagainstover-current,  
reverse battery, and positive and negative voltage transients.  
The SPX2940 is offered in 3-pin TO-220 & TO-263 packages. For a 3A version, refer to the  
SPX29300 data sheet.
