The TPS71530DCKR is a 3V fixed output low-dropout (LDO) Linear Regulator provide the benefits of high input voltage and low-power operation. The device is stable with any capacitor greater than or equal to 0.47µF. The low-dropout (LDO) voltage and low quiescent current allow operation at extremely low power levels. Therefore, the devices are ideal for powering battery management ICs. Specifically, because the devices are enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously operating battery charging ICs. The usual PNP pass transistor has been replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the low-dropout (LDO) voltage, typically 415mV at 50mA of load current, is directly proportional to the load current. The low quiescent current is stable over the entire range of output load current.
