Starting with 9, a bar on top of 9 is for production

year 2005, and underlined 9 is for year 2006. The

naming

pattern

continues

with

consecutive

characters for later years.

The middle character (A-F) is the output voltage

of production.

L means the package is SOT-23-5L.

The last character is the week code. (A-Z: 1-26,

a-z: 27-52).

A dot on top right corner is for lead-free process.
