SPX2940 1A 低漏失电压调节器
The SPX2940 is a 1A, accurate voltage regulators with a low drop out voltage of 280mV (typical) 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 overcurrent, 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.
