As a developer, I often attempt to follow best practices for developing against/using databases, however, it is rarely within my remit to configure or maintain a database. In fact usually I have restricted or no access to database servers. (I can hear the DBAs cheer as do I. I usually have enough on my plate and am aware I do not have the expertise of a DBA so how on earth am I supposed to perform the duties of a DBA to the standards I demand of myself and would expect my clients to demand!!!)

That said, I cannot remember one instance of the application of TDE or the use of any other encryption beyond the encrypting of passwords.
