Typical Operating Characteristics.
Use a 0.01µF bypass capacitor at BP for low output volt-
age noise. Increasing the capacitance will slightly
decrease the output noise, but increase the start-up time.
Values above 0.1µF provide no performance advantage
and are not recommended (see Shutdown Exit Delay
graphs in the Typical Operating Characteristics).
The MAX8877/MAX8878 are designed to deliver low
dropout voltages and low quiescent currents in battery-
powered systems. Power-supply rejection is 63dB at
low frequencies and rolls off above 10kHz. See the
Power-Supply Rejection Ratio Frequency graph in the
Typical Operating Characteristics.
When operating from sources other than batteries,
improved supply-noise rejection and transient response
can be achieved by increasing the values of the input
and output bypass capacitors, and through passive fil-
tering techniques. The Typical Operating Charac-
teristics show the MAX8877/MAX8878’s line- and load-
transient responses.

two components of the output response: a DC shift
from the output impedance due to the load current
change, and the transient response. Typical transient
for a step change in the load current from 0mA to 50mA
is 12mV. Increasing the output capacitor’s value and
decreasing the ESR attenuates the overshoot.
For output voltage greater than the minimum input volt-
age (2.5V), the regulator’s minimum input-output volt-
age differential (or dropout voltage) determines the
lowest usable supply voltage. In battery-powered sys-
tems, this will determine the useful end-of-life battery
voltage. Because the MAX8877/MAX8878 use a P-
channel MOSFET pass transistor, their dropout voltage
is a function of drain-to-source on-resistance (R
multiplied by the load current (see Typical Operating
Characteristics).
