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 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.
