DESCRIPTION

The SS6734G is a 3-pin low-dropout linear
regulator with superior characteristics, which
include zero base current loss, very low drop­out voltage, and output voltage accuracy of 2%.
Typical ground current remains approximately
55µA, 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.

The SS6734G is available in SOT-23-3, SOT-89,
and TO-92 packages.

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.
Note 2: Guaranteed by design.
Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Note 4: Current limit is measured by pulsing a short time.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops

100mV.
