■ Standard TO-220 and TO-263
The SPX2941 is a 1A, accurate voltage regulator with a low drop out voltage of 280mV(typ.) at
1A. These regulators are specifically designed for low voltage applications that require a low
dropout voltage and a fast transient response. They are fully fault protected against over-current,
reverse battery, and positive and negative voltage transients. The SPX2941 is offered in 5-pin
TO-220 & TO-263 packages. For a 3A version, refer to the SPX29300 data sheet.
FEATURES
■ Adjustable Output Down To 1.25V
■ Low Quiescent Current
■ Guaranteed 1.5A Peak Output Current
■ Low Dropout Voltage of 280mV @ 1A
■ Extremely Tight Load and Line
■ Extremely Fast Transient Response
■ Reverse-battery Protection
■ Internal Thermal and Current Limit
■ Zero Current Shutdown
