I agree with Mini-Mitch. There are a couple other episodes - the Doctor drowning and dying too fast to regenerate in Turn Left; River telling the Doctor that linking to a computer would burn out both his hearts and kill him, rendering regeneration impossible, in Forest of the Dead; the astronaut suit taking another shot to kill the "Doctor" as he was regenerating in The Impossible Astronaut. The Tenth Doctor says it's like death because that particular body and personality are gone, but that comes directly after Wilfred Mott reminds Ten that he explained regeneration in the context of escaping death.
