General Description
The GS7168 can deliver up to 0.8A of output
current with a typical dropout voltage of only
100mV using internal n-channel MOSFETs. The
linear regulator uses a separate VDD supply to
power the control circuitry and drive the Internal
n-channel MOSFETs. The output voltage is
adjustable from 0.8V to the voltage that is very
close to VIN.
The GS7168 allows the use of low-ESR ceramic
capacitor as low as 10uF. Moreover the IC
provides good performance on both line transient
response and load transient response.
The GS7168 provides foldback over current limit
and thermal shutdown to prevent the linear
regulator from damage. Built-in soft-start
minimizes stress on the input power source by
reducing capacitive inrush current on start-up.
During start-up, POK remain low until the output
reaches 92% of its rating value.
The GS7168 is available in TDFN8-2X2 package.

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the
device. These are for stress ratings. Functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may remain possibility to
affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended.
Note 3. θJA is measured in the natural convection at TA=25°C on a high effective thermal conductivity test
board (4 Layers, 2S2P) of JEDEC 51-7 thermal measurement standard. The case point of θJC is
on the expose pad for TDFN8-2x2 package.
Note 4. The device is not guaranteed to function outside its operating conditions.
Note 5. VDD should be 1.5V higher than the output voltage, VDD> 1.5V+Vout
Note 6.Regulation is measured at constant junction temperature by using a 2ms current pulse. Devices
are tested for load regulation in the load range from 1mA to 0.8A.
Note 7. The Dropout voltage is defined as VIN-VOUT, which is measured when VOUT is 0.98*VOUT(NORMAL).
The dropout voltage is measured at constant junction temperature by using a 2ms current pulse.
