SS6734G
300mA Low Dropout Linear Regulator
FEATURES
DESCRIPTION
Low dropout voltage of 470mV at an output
The SS6734G 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
55mA, for loads ranging from zero to maximum.
Dropout voltage at an output current of 300mA
is exceptionally low. Built-in output current
limiting and thermal limiting provide maximum
protection against fault conditions.
current of 300mA (3.0V output version).
Guaranteed 300mA output current.
Low ground current of 55mA.
Output voltage accuracy of 2% at 1.8V/ 2.0V /2.5V
/2.7V/ 3.0V/ 3.3V/ 3.5V/ 3.7V/ 3.8V/ 5.0V/5.2V
Only needs 1mF output capacitor for stability.
Current and thermal limiting.
Pb-free, RoHS compliant.
APPLICATIONS
CD-ROM Drivers.
LAN Cards.
The SS6734G is available in RoHS-compliant
SOT-23-3, SOT-89, and TO-92 packages.
Microprocessors.
DRAM Modules.
Wireless Communication Systems.
Battery Powered Systems.

Note 1:
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.
Note 2:
Note 3:
Note 4:
Note 5:
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.
