Figure 3. Power Operating Regions: Maximum Output Current
vs. Input-Output Voltage Difference
Figure 2. Adjustable Output Using External Feedback Resistors
response graphs (see the Typical Operating
Characteristics ) 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
current 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 differential
(dropout voltage) determines the lowest usable supply
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 the Typical
Operating Characteristics ):
V DROPOUT = V IN - V OUT = R DS(ON) ? I OUT
