A regulator’s minimum input-output voltage differential,
or dropout voltage, determines the lowest usable supply
voltage. In battery-powered systems, this will determine
the useful end-of-life battery voltage. Because the
MAX603/MAX604 use a P-channel MOSFET pass tran-
sistor, their dropout voltage is a function of r
plied by the load current (see Electrical Characteristics ).
Quickly stepping up the input voltage from the dropout
voltage can result in overshoot. This occurs when the
pass transistor is fully on at dropout and the IC is not
given time to respond to the supply voltage change.
Prevent this by slowing the input voltage rise time.
