TPS76728QDG4 Description
Because the PMOS device behaves as a low-value resistor.the dropout voltage is very low(typically 230mV at an output current of 1 A for the TPS76750)and is directly proportional to the output current.Additionallysince the PMOS pass element is a voltage-driven device. the quiescent current is very low and independent of outout oadina (tvpically 85 uA ove the full ranae of output current.0 mA to 1A)These two key specifications vield a sianificant improvement in oneratina life for batfery-nowered svstemshis 00 family also features a seen modeanpving ahiah sianal to FN (enabe shuts down the regulator,reducing the quiescent current to 1uA at T=25°℃.
