... TO-220, TO-263 and TO-252 packages available GENERAL DESCRIPTION The The AMS1085 series of adjustable and fixed voltage regulators are designed to provide 3A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.5V at maximum output current, decreasing at lower load currents. ...

... Figure 1. Basic Adjustable Regulator Load Regulation True remote load sensing it is not possible to provide, because the AMS1085 is a three terminal device. The resistance of the wire connecting the regulator to the load will limit the load regulation. The data sheet specification for load regulation is measured at the bottom of the package ...
