Power Load Distribution Switch IC, Active High, 1 Channel Output, 5.5V in, 500mA, 0.17 Ohm, SOT-23-5 - 

The MIC2005A-1YM5 TR is a fixed and adjustable current limiting power Distribution Switch designed for general purpose application. It is thermally protected and will shutdown should their internal temperature reach unsafe levels, protecting both the device and the load, under high current or fault conditions. It features include fault reporting, fault blanking to eliminate noise-induced false alarms, output slew rate limiting, under-voltage detection, automatic-ON output and enable pin with choice of either active low or active high enable. The FET is self-contained with a fixed- or user-adjustable current limit. Ideal for any system where current limiting and power control are desired.
