These Output and Adjustable Versions devices are capable of supplying 1.5 A of output • Open Drain Power-Good (PG) Status Output current with a dropout of 160 mV (TPS75133Q, (TPS751xxQ) TPS75333Q). Quiescent current is 75 μA at full load • Open Drain Power-On Reset With 100ms Delay and drops down to 1 μA when the device is disabled. (TPS753xxQ) These devices are designed to have fast transient response for larger load current changes. • Dropout Voltage Typically 160 mV at 1.5 A (TPS75133Q) Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically • Ultralow 75-μA Typical Quiescent Current 160 mV at an output current of 1.5 A for the • Fast Transient Response TPS75x33Q) and is directly proportional to the output • 2% Tolerance Over Specified Conditions for current. Additionally, because the PMOS pass Fixed-Output Versions element is a voltage-driven device, the quiescent current is very low and independent of output loading • 20-Pin TSSOP PowerPAD™ (PWP) Package (typically 75 μA over the full range of output current, • Thermal Shutdown Protection 1 mA to 1.5 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. • Telecom The device is enabled when EN is connected to a • Servers low-level input voltage. This LDO family also features • DSP, FPGA Supplies 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 (Fixed Voltage Options) (1) See Application Information for capacitor selection details. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
