Output Capacitor
To ensure the stability of the SPX1117, an
output capacitor of at least 2.2F (tantalum or
ceramic) or 10F (aluminum) is required. The
value may change based on the application
requirements of the output load or temperature
range. The value of ESR can vary based on the
type of capacitor used in the applications to
guarantee stability. The recommended value
for ESR is 0.5 or less. A larger value of
output capacitance (up to 100F) can improve
the load transient response.
Soldering Methods
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.
