Power Dissipation Consideration
For the SOT23 package, any pin except the SET pin
can be used as a heatsink. If the SET pin is used as a
heatsink, excessive parasitic capacitance can affect
stability. For the QFN package, the exposed metal pad
on the back side of a package connects to GND of the
chip. This metal pad can be used as a heatsink.
UCSP Consideration
For general UCSP package information and PC layout
considerations, refer to Maxim Application Note:
Wafer-
Level Chip-Scale Package
.
UCSP Reliability
The chip-scale package (UCSP) represents a unique
packaging form factor that might not perform equally to
a packaged product through traditional mechanical
reliability tests. CSP reliability is integrally linked to the
user
’
s assembly methods, circuit-board material, and
usage environment. The user should closely review
these areas when considering a CSP package.
Performance through operating life test and moisture
resistance remains uncompromised, because it is pri-
marily determined by the wafer-fabrication process.
Mechanical stress performance is a greater considera-
tion for a CSP package. CSPs are attached through
direct solder contact to the user
’
s PC board, forgoing
the inherent stress relief of a packaged product
’
s lead
frame. Solder-joint contact integrity must be considered.

’
s qualification plan, test data, and
recommendations are detailed in the UCSP application
note on Maxim
