put capacitors with an ESR of 0.1
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 10F. Connect CIN and
COUT as close to the MAX8887/MAX8888 as possible to
minimize the impact of PC board trace inductance.
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.
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
(RDS(ON)) multiplied by the load current (see Typical
Operating Characteristics).
