Texas Instruments TPS75418

Single Output LDO 2.0A Fixed(1.8V) PowerGood (PG) Output Fast Transient Response
The TPS752xxQ and TPS754xxQ devices 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 (TPS75233Q, TPS75433Q). Quiescent current is 75 A at full load and drops down to 1 A when the device is disabled. These devices 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 TPS75x33Q) and is directly proportional to the output current. Additionally, because 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 2 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. The device is enabled when ENENRESETRESETRESET
