Things of interest:

TL431ACLPG shunt regulator diode - given a Vref and a V, if V <= Vref then Vout = V.
LMS33460 - similar sort of thing to above, but V is fixed to 3V; also has built-in hysteresis to prevent it flapping due to noise.

NX5P2924UK - logic controlled power switch; can be used to turn chunks of circuitry on and off
G6K SMD Relay -- small, latching relay
UB20M - voltage detector IC, can be used to create zero-power monitor circuits that trigger wakeup on sensor reading
