MAX1735 output noise is typically 160µV
suitably low for most applications. See the Output
Noise vs. Frequency plot in the Typical Operating
Characteristics.
The MAX1735 is optimized for battery-powered equip-
ment, with low dropout voltage and low quiescent cur-
rent. It maintains good transient response, AC rejection,
and noise characteristics even near dropout. See
Power-Supply Rejection Ratio vs. Frequency in the
Typical Operating Characteristics. When operating
from very noisy sources, supply noise rejection and
transient response can be improved by increasing the
input and output capacitance, and by employing pas-
sive postfiltering.

A regulator’s minimum input-to-output voltage differen-
tial dropout voltage determines the lowest usable sup-
ply voltage for an application. In battery-powered
systems, this determines the useful end-of-life battery
voltage. Since the MAX1735’s pass element is an
N-channel MOSFET, dropout voltage is the product of

MAX1735 operating (ground pin) current typically
remains below 125µA at full load in dropout.
