DESCRIPSION
The LM1117Q is a low power positive-voltage regulator designed to meet 1A output current and comply with
SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for use in batterypowered applications, as active terminators for the SCSI bus, and portable computers. The LM1117Q features
very low quiescent current and very low dropout voltage of 1V at a full load and lower as output current
decreases. LM1117Q is available as an adjustable or fixed 1.2V, 1.5V, 1.8V, 2.5V, 2.85, 3.3V, and 5.0V output
voltages. The LM1117Q is offered in a 3-pin surface mount package SOT-223. The output capacitor of 10㎌ or
larger is needed for output stability of LM1117Q as required by most of the other regulator circuits.

APPLICATION INFORMATION
Maximum Output Current Capability
The LM1117Q can deliver a continuous current of 1A over the full operating junction temperature range.
However, the output current is limited by the restriction of power dissipation which differs from packages. A heat
sink may be required depending on the maximum power dissipation and maximum ambient temperature of
application. With respect to the applied package, the maximum output current of 1A may be still undeliverable
due to the restriction of the power dissipation of LM1117Q. Under all possible conditions, the junction
temperature must be within the range specified under operating conditions. The temperatures over the device
are given by:
TC = TA + PD X θCA / TJ = TC + PD X θJC / TJ = TA + PD X θJA
where TJ is the junction temperature, TC is the case temperature, TA is the ambient temperature, PD is the total
power dissipation of the device, θCA is the thermal resistance of case-to-ambient, θJC is the thermal resistance of
junction-to-case, and θJA is the thermal resistance of junction to ambient. The total power dissipation of the
device is given by:
PD = PIN – POUT = (VIN X IIN)–(VOUT X IOUT)
= (VIN X (IOUT+IGND)) – (VOUT X IOUT) = (VIN - VOUT) X IOUT + VIN X IGND
where IGND is the operating ground current of the device which is specified at the Electrical Characteristics. The
maximum allowable temperature rise (TRmax) depends on the maximum ambient temperature (TAmax) of the
application, and the maximum allowable junction temperature (TJmax):
TRmax = TJmax – TAmax
The maximum allowable value for junction-to-ambient thermal resistance, θJA, can be calculated using the
formula:
θJA = TRmax / PD = (TJmax – TAmax) / PD
LM1117Q is available in SOT223 package. The thermal resistance depends on amount of copper area or heat
sink, and on air flow. If the maximum allowable value of θJA calculated above is over 137°C/W for SOT-223
package, no heat sink is needed since the package can dissipate enough heat to satisfy these requirements. If
the value for allowable θJA falls near or below these limits, a heat sink or proper area of copper plane is required.
In summary, the absolute maximum ratings of thermal resistances are as follow:
