These devices are capable of supplying 2 A of output current with a dropout of 210 mV (TPS75233Q, TPS75433Q). Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. TPS752xxQ and TPS754xxQ are designed to have fast transient response for larger load current changes.
