SPX29500T-L-3-3 Datasheet(HTML) 1 Page - Exar Corporation |
1 / 9 page DESCRIPTION FEATURES ■ Adjustable Output Down to 1.25V ■ 1% Output Accuracy ■ Output Current of 5A ■ Low Dropout Voltage: 420mV @ 5A ■ Tight Line Regulation: 0.06% ■ Load Regulation: 0.2% ■ Fast Transient Response ■ Reverse-Battery Protection ■ Current Limit and Thermal Protection The SPX29501/02 are 5A highly accurate voltage regulators with a low dropout voltage of 420mV @ 5A. 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. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. Other features include Enable, and Error Flag. The SPX295001/02 are offered in 5-pin TO-220 & TO-263 packages. For a 1.5A version, refer to the SPX29150 data sheet. For a 3A version, refer to the SPX29300 datasheet.
