DESCRIPTIO The LT®3150 drives a low cost external N-channel MOSFET as a source follower to produce a fast transient response, very low dropout voltage linear regulator. Selection of the N-channel MOSFET RDS(ON) allows dropout voltages below 300mV for low VIN to low VOUT applications. A precision 1.21V reference accommodates low voltage supplies.
