Description (continued)
All family members are offered in two package styles. The LH is a
SOT-23W style, miniature, low profile package for surface-mount
applications. The UA is a 3-pin, ultra-mini, single inline package
(SIP) for through-hole mounting. Both packages are lead (Pb) free,
with 100% matte tin leadframe plating.
