Noise, PSRR, and Transient Response
MAX1735 output noise is typically 160μV
RMS
. This is
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.
Dropout Voltage
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
R
DS(ON)
and the load current; see
Electrical
Characteristics
and Dropout Voltage vs. Load Current
in the
Typical Operating Characteristics
for details. The
MAX1735 operating (ground pin) current typically
remains below 125μA at full load in dropout.
