DESCRIPTION
The TPS753xx Q and TPS751xx Q devices 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 m V (TPS75133Q, TPS75333Q). Quiescent current is 75 μA at full load and drops down to 1 μA 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 160 m V at an output current of 1.5 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 μA over the full range of output current, 1 m A 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 input 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 μA at TJ = +25°C. blank blank
