150mA, Low-Dropout Linear Regulator
with Power-OK Output
PSRR and Operation from Sources
Other than Batteries
The MAX8885 is designed to allow low dropout voltages
and low quiescent currents in battery-powered systems.
Power-supply rejection is 60dB at low frequencies (see
the Power-Supply Rejection Ratio vs. Frequency graph
in the Typical Operating Characteristics ).
Improve supply-noise rejection and transient response
by increasing the values of the input and output bypass
capacitors. The typical operating characteristics show
the MAX8885 ’ s line- and load-transient responses.
Load-Transient Considerations
The MAX8885 ’ s load-transient response graphs (see
Typical Operating Characteristics ) show three compo-
put capacitor is chosen to comply with the Region of
Stable C OUT ESR vs. Load Current graph.
Dropout Voltage
A regulator ’ s minimum input-output voltage differential
(or dropout voltage) determines the lowest usable sup-
ply voltage. In battery-powered systems, this will deter-
mine the useful end-of-life battery voltage. Because the
MAX8885 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 ).

nents of the output response. The first (and most signifi-
cant) component is the abrupt drop in output voltage
due to the capacitor ’ s ESR. The magnitude of the voltage

Chip Information
drop is directly proportional to the output capacitor's
ESR and the size of the load transient and is indepen-
dent of the regulator ’ s transient response. The second
component is the output voltage recovery, which is a
function of the regulator ’ s loop response and the capaci-
tance at the output. The third component is a DC shift in
the output voltage resulting from the regulator ’ s finite out-
put impedance. To improve the MAX8885 ’ s load-tran-
sient response, increase the output capacitor ’ s value
and decrease its ESR. Take care to ensure that the out-
