This might be an embarrassingly easy question, but I always get confused about
it. When are all monos in an algebraic category regular (or more generally,
when are all monos in a regular category regular)? What are some sensible
sufficient or necessary conditions?

For example, all monos in the category of groups are regular. How about the
category of lattices, or lattices with a top element?
