The TPS752xx and TPS754xx are low-dropout regulators with integrated power-on reset and power good (PG) funcTIons, respecTIvely. These devices are capable of supplying 2 A of output current with a dropout of 210 mV (TPS75233, TPS75433). Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. TPS752xx and TPS754xx are designed to have fast transient response for larger load current changes.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 210 mV at an output current of 2 A for the TPS75x33) and is directly proporTIonal to the output current. AddiTIonally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 75 µA over the full range of output current, 1 mA to 2 A).
