1.5A Low Dropout Voltage Regulator
Product Description
The GS1086L is a low dropout three-terminal
regulator with 1.5A output current capability. In
order to obtain lower dropout voltage and fast
transient response, this is critical for low voltage
applications. The GS1086L has been optimized.
The device is available in an adjustable version
and fixed output voltage of 1.5V, 1.8V, 2.5V, 3.3V
and 5V. Dropout voltage is guaranteed at a
maximum of 1.3V at 1.5A.
Current limit is trimmed to ensure specified output
current and controlled short circuit current.
On-chip thermal limiting provides protection
against any combination of overload that would
create excessive junction temperatures.
The GS1086L is available in the three leads
SOT-223, TO-252 and TO-263 surface mount
packages.

Load Regulation
True remote load sensing it is not possible to provide, because the GS108X is a three terminal device. The
resistance of the wire connecting the regulator to the load will limit the load regulation. The data sheet specification
for load regulation is measured at the bottom of the package. Negative side sensing is a true Kelvin connection, with
the bottom of the output divider returned to the negative side of the load.
The best load regulation is obtained when the top of the resistor divider R1 is connected directly to the case not to
the load. If R1 were connected to the load, the effective resistance between the regulator and the load would be:
RP x ( R2+R1/R1 ) , RP = Parasitic Line Resistance
Connected as shown, RP is not multiplied by the divider ratio.
In the case of fixed voltage devices the top of R1 is connected Kelvin internally, and the ground pin can be used for
negative side sensing.

Thermal Considerations
The GS108X series have internal power and thermal limiting circuitry designed to protect the device under
overload conditions. However maximum junction temperature ratings of 125ºC should not be exceeded under
continuous normal load conditions.
Careful consideration must be given to all sources of thermal resistance from junction to ambient. For the
surface mount package SOT-223 additional heat sources mounted near the device must be considered. The
heat dissipation capability of the PC board and its copper traces is used as a heat sink for the device. The
thermal resistance from the junction to the tab for the GS108X is 15ºC /W. Thermal resistance from tab to ambient
can be as low as 30ºC /W.
The total thermal resistance from junction to ambient can be as low as 45ºC /W. This requires a reasonable sized
PC board with at least on layer of copper to spread the heat across the board and couple it into the surrounding air.
Experiments have shown that the heat spreading copper layer does not need to be electrically connected to the
tab of the device. The PC material can be very effective at transmitting heat between the pad area, attached to the
pad of the device, and a ground plane layer either inside or on the opposite side of the board. Although the actual
thermal resistance of the PC material is high, the Length/Area ratio of the thermal resistance between layers is
small. The data in Table 1, was taken using 1/16” FR-4 board with 1 oz. copper foil, and it can be used as a rough
guideline for estimating thermal resistance.
For each application the thermal resistance will be affected by thermal interactions with other components on the
board. To determine the actual value some experimentation will be necessary.
The power dissipation of the GS108X is equal to:
PD = ( VIN - VOUT ) ( IOUT )
Maximum junction temperature will be equal to:
TJ = TA (MAX) + PD (Thermal Resistance (junction-to-ambient))
Maximum junction temperature must not exceed 125 ºC.
