AS1117

Maximum Junction Temperature range:

APPLICATION NOTES EXTERNAL

CAPACITOR

T_J= T_ambient(max) + P_D* thermal resistance (Junction-to-

ambient)

To ensure the stability of the AS1117 an output capacitor of

at least 10µF (tantalum)or 50µF (aluminum) is required. The

value may change based on the application requirements on

the output load or temperature range. The capacitor

equivalent series resistance (ESR) will effect the AS1117

stability. The value of ESR can vary from the type of

capacitor used in the applications. The recommended value

for ESR is 0.5Ω. The output capacitance could increase in

size to above the minimum value. The larger value of output

capacitance as high as 100µF can improve the load transient

response.

Maximum Junction temperature must not exceed the 125°C.

50 X 50 mm

35 X 17 mm

SOLDERING METHODS

The AS1117 SOT-223 package is designed to be compatible

with infrared reflow or vapor-phase reflow soldering

techniques. During soldering the non-active or mildly active

fluxes may be used. The AS1117 die is attached to the

heatsink lead which exits opposite the input, output, and

ground pins.

16 X 10 mm

Hand soldering and wave soldering should be avoided since

these methods can cause damage to the device with excessive

Fig. 1. Substrate Layout for SOT-223

thermal gradients on the package.

The SOT-223

recommended soldering method are as follows: vapor phase

reflow and infrared reflow with the component preheated to

within 65°C of the soldering temperature range.

THERMAL CHARACTERISTICS

The thermal resistance of AS1117 is 15°C/W from junction

to tab and 31 °C/W from tab to ambient for a total of 46

°C/W from junction to ambient. The AS1117 features the

internal thermal limiting to protect the device during

overload conditions. Special care needs to be taken during

continuos load conditions the maximum junction temperature

does not exceed 125 °C.

Taking the FR-4 printed circuit board and 1/16 thick with 1

ounce copper foil as an experiment (fig.1 & fig.2), the PCB

material is effective at transmitting heat with the tab attached

to the pad area and a ground plane layer on the backside of

the substrate. Refer to table 1 for the results of the

experiment.

The thermal interaction from other components in the

application can effect the thermal resistance of the AS1117.

The actual thermal resistance can be determined with

experimentation. AS1117 power dissipation is calculated as

follows:

P_D= (V_IN- V_OUT)(I_OUT

)
