Now Available in Lead Free Packaging DESCRIPTION The SPX29302A is a 3A, highly accurate voltage regulator with a low drop out voltage of 370mV (typical) @ 3A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. Fault protection features include over-current, reverse battery, and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. The SPX29302A is offered in 5-pin TO-220 & TO-263 packages. TYPICAL APPLICATION S CIRCUIT 1 SPX29302A 4 + 2 GND 3 5 ADJ + R1 V OUT 10µF V IN 6.8µF R2 Figure 1.
