These devices are capable of supplying 3 A of output current with a dropout of 150 mV (TPS75733). Therefore, the device is capable of performing a 3.3-V to 2.5-V conversion. Quiescent current is 125 µA at full load and drops down to less than 1 µA when the device is disabled. The TPS757xx is designed to have fast transient response for large load current changes. t − Time − µs TPS75715 LOAD TRANSIENT RESPONSE −100 0 060 40 20 80 100 140 120 160 180 200 0 50 −50 VO = 1.5 V Co = 100 µF −150 2 di dt + 0.75 A ms 4 100 150 0 50 100 150 200 250 −40 −25 −10 5 20 35 50 65 80 95 110 125 TJ − Junction Temperature − °C TPS75733 DROPOUT VOLTAGE vs JUNCTION TEMPERATURE IO = 3 A VO = 3.3 V 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.
