Noise, PSRR, and Transient Response
The MAX8887/MAX8888 are designed to operate with
low dropout voltages and low quiescent currents in bat-
tery-powered systems while still maintaining excellent
noise, transient response, and AC rejection. See the
Typical Operating Characteristics
for a plot of power-
supply rejection ratio (PSRR) versus frequency. When
operating from noisy sources, improved supply-noise
rejection and transient response can be achieved by
increasing the values of the input and output bypass
capacitors and through passive filtering techniques.
MAXIMUM OUTPUT CURRENT (mA)
put capacitors with an ESR of 0.1Ω or less to ensure sta-
bility and optimum transient response. Surface-mount
ceramic capacitors have very low ESR and are com-
monly available in values up to 10µF. Connect C

and

as close to the MAX8887/MAX8888 as possible to
minimize the impact of PC board trace inductance.

Input-Output (Dropout) Voltage
A regulator’s minimum input-to-output voltage differen-
tial (dropout voltage) determines the lowest usable sup-
ply voltage at which the output is regulated. In
battery-powered systems, this determines the useful
end-of-life battery voltage. The MAX8887/MAX8888 use
a P-channel MOSFET pass transistor. Its dropout volt-
age is a function of drain-to-source on-resistance
(R
DS(ON)
) multiplied by the load current (see the
Typical Operating Characteristics).
