Figure 3. Power Operating Regions: Maximum Output Current
vs. Supply Voltage
Figure 2. Adjustable Output Using External Feedback Resistors
response graphs (see Typical Operating Characteris-
tics ) show two components of the output response: a
DC shift from the output impedance due to the load
current change, and the transient response. A typical
transient overshoot for a step change in the load cur-
rent from 5mA to 500mA is 40mV. Increasing the output
capacitor ’ s value and decreasing the ESR attenuates
the overshoot.
Input-Output (Dropout) Voltage
A regulator ’ s minimum input-to-output voltage differen-
tial (dropout voltage) determines the lowest usable sup-
ply voltage. In battery-powered systems, this
determines the useful end-of-life battery voltage.
Because the MAX1806 uses a P-channel MOSFET pass
transistor, its dropout voltage is a function of drain-to-
source on-resistance (R DS(ON) ) multiplied by the load
current (see Typical Operating Characteristics ):
V DROPOUT = V IN - V OUT = R DS(ON) ? I OUT
