(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device  eliability.

The TPS71550-Q1 low-dropout (LDO) voltage regulators offer the benefits of high input voltage, LDO 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 LDO voltage and low quiescent current allow operations at extremely low power levels. Therefore, the TPS71550-Q1 are ideal for powering battery-management ICs. Specifically, since the devices are enabled as soon as the applied voltage reaches the minimum input voltage, the output of TPS71550-Q1 is quickly available to power continuously operating battery-charging ICs.

The usual PNP pass transistor TPS71550-Q1 has been replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the LDO voltage, typically 415 mV at 50 mA of load current, is directly proportional to the load current. The low quiescent current of TPS71550-Q1 (3.2 A typ) is stable over the entire range of output load current (0 mA to 50 mA).
