DESCRIPTION
The
SS6735G
is a 3-pin low-dropout linear
regulator
with
superior characteristics,
which
include zero base current loss, very
low drop-
out voltage, and output
voltage accuracy of 2%.
Typical ground current remains approximately
65µA, for loads ranging from
zero to maximum.
Dropout voltage at
an output current of 100mA
is
exceptionally low. Built-in
output current
limiting and thermal limiting
provide maximum
protection
against fault conditions.
Pb-free, RoHS compliant.
APPLICATIONS
CD-ROM Drivers.
LAN Cards.
Microprocessors.
DRAM
Modules.
Wireless Communication Systems.
Battery Powered Systems.
The SS6735G is available in RoHS-compliant
SOT-23-3, SOT-223, SOT-89, and TO-252
packages.

Note 1:

Note 4:
Note 5:
Specifications are guaranteed by Statistical Quality Control (SQC),
not by 100%
production
testing, over the
operating temperature range from -40°C to 85°C.
Guaranteed by design.
Regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Current limit is measured by pulsing a short time.
Dropout voltage is defined as the input to output differential at which the output voltage drops
100mV below the value of the output voltage measured with a 1V differential.
