The TPS715Axx low-dropout (LDO) voltage regulators offer the benefits of high input voltage, low-dropout voltage, low-power operation, and miniaturized packaging. The devices, which operate over an input range of 2.5 V to 24 V, are stable with any capacitor ( 0.47 F). The high maximum input voltage combined with excellent power dissipation capability makes this part particularly well-suited to industrial and automotive applications. A PMOS pass element behaves as a low-value resistor. The low dropout voltage, typically 670 mV at 80 mA of load current, is directly proportional to the load current. The low quiescent current (3.2 A typically) is nearly constant over the entire range of output load current (0 mA to 80 mA).
