Component qualification in accordance with JEDEC and industry  
standards to ensure reliable operation over an extended  
temperature range. This includes, but is not limited to, Highly  
Accelerated Stress Test (HAST) or biased 85/85, temperature  
cycle, autoclave or unbiased HAST, electromigration, bond  
intermetallic life, and mold compound life. Such qualification  
testing should not be viewed as justifying use of this component  
beyond specified performance and environmental limits.

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.  
J
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.
