Maxim Integrated 

5V/3.3V or Adjustable, Low-Dropout,

Low IQ, 500mA Linear Regulators

Input-Output (Dropout) Voltage

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 rDS(ON) multi-

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.
