APPLICATION INFORMATION
O
To ensure the stability of the SPX1117, an
output capacitor of at least 2.2µF (tantalum or
ceramic) or 10µF (aluminum) is required. The
value may change based on the application
requirements
temperature range. The value of ESR can vary
based on the type of capacitor used in the
applications
recommended value for ESR is 0.5Ω or less. A
larger value of output capacitance (up to
100µF)
response.

The SPX1117 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 SPX1117 die is
attached to the heatsink lead which exits
opposite the input, output, and ground pins.
Hand soldering and wave soldering should be
avoided
damage to the device with excessive thermal
gradients
recommended
follows: vapor phase reflow and infrared
reflow with the component preheated to within
65°C of the soldering temperature range.
T
The thermal resistance of SPX1117 (SOT-223
package) 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 (Table 1). The
SPX1117 features the internal thermal limiting
to
conditions. Special care needs to be taken
during continuous load conditions such that
the maximum junction temperature does not
exceed 125 °C. Thermal protection is activated
at >155°C and deactivated at <140 °C.
