Description

The TPS75301QPWPRQ1, TPS753xxQ and TPS751xxQ are low dropout regulators with integrated power-on reset and power-good (PG) functions respectively. These devices are capable of supplying 1.5 A of output current with a dropout of 160 mV (TPS75133Q, TPS75333Q). Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. TPS751xxQ and TPS753xxQ 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 160 mV at an output current of 1.5 A for the TPS75x33Q) 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 1.5 A). These two key specifications yield a significant improvement in operating life for battery-powered systems.
