These devices provide a typical accuracy of 0.5%. The TLV717P series offer current foldback that throttles down the output current with a decrease in load resistance. The typical value at which current foldback initiates is 350 mA; the typical value of the output short current limit value is 40 mA. Furthermore, these devices are stable with an effective output capacitance of only 0.1 µF. This feature enables the use of cost-effective capacitors that have higher...
