Automotive Catalog Fast-transient-response 1.5-a Low-drop Voltage Regulator

  The 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 ?A at full load and drops down to 1 ?A 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 ?A 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. The device is enabled when EN is connected to a low level voltage. This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the Regulator reducing the quiescent current to less than 1 ?A at TJ = 25?C. For the TPS751XXQ the power-good terminal (PG) is an active high, open drain output, which can be used to implement a power-on reset or a low-battery indicator.
