General Description
The GS7136 can deliver up to 0.6A of continuous
output current with a typical dropout voltage of
only 90mV using internal n-channel MOSFETs.
The linear regulator uses a separate VDD supply
to power the control circuitry and drive the Inter-
nal n-channel MOSFETs. The output voltage is
adjustable from 0.8V to the voltage that is very
close to VIN.
The GS7136 allows the use of low-ESR ceramic
capacitor as low as 10uF. Moreover the IC
provide good performance on both line transient
response and load transient response.
The GS7136 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 GS7136 is available in SOT-23-6 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 PSOP-8 package.

Input Capacitor selection
Bypass VIN to ground with a 10uF or greater
capacitor. Bypass VDD to ground with a 1uF
capacitor for normal operation in most appli-
cations. Ceramic, tantalum or aluminum elec-
trolytic capacitors may be selected for input
capacitor. However ceramic capacitors are
recommended due to their significant cost and
space savings. Place the capacitors physically as
close as possible to the device with wide and
direct PCB traces.
Power Dissipation and Layout Considerations
Although internal thermal limiting function is
integrated in GS7136, continuously keeping the
junction near the thermal shutdown temperature
may possibly affect device reliability. For
continuous operation, it is highly recommended to
keep the junction temperature below the
maximum operation junction temperature 125°C
for maximum reliability.
The power dissipation definition in device is:
PD = (VIN − VOUT) x IOUT + VDD x IQ
The maximum power dissipation can be
calculated as:
PD(MAX) = ( TJ(MAX) − TA ) / θJA
Where TJ(MAX) is the maximum operation junction
temperature 125°C, TA is the ambient
temperature and the θJA is the junction to ambient
thermal resistance.
