Seamless Microsystems’ (SMI) SMBGREF28 is a silicon-proven bandgap reference with accurate voltage output
and optional current outputs and digital trimming capabilities. Using only a 0.9V core supply, the 0.45V reference
shows exceptional stability over a temperature range of 0 to 100C, while exhibiting only a 3% error across process,
without any digital tuning.
