description

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 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.

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

µA at T = 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.
