TPS2150IPWP Datasheet PDF - TI

●DESCRIPTION

●The TPS2140/41/50/51 is a USB 1.0 and 2.0 Specification-compatible IC containing a dual-current limiting power switch and an adjustable low dropout regulator (LDO). Both the switch and LDO limit inrush current by controlling the turnon slew rate. The unique dual-current-limiting feature of the switch allows USB peripherals to utilize high-value capacitance at the output of the switch, while keeping the inrush current low. During turnon, the switch limits the current delivered to the capacitive load to less than 100 mA.
