DESCRIPTION
The TSM112 integrated circuit incorporates all
sensing circuitry to regulate and protect from over
voltage and under voltage a multiple output power
supply (3.3V, 5V and 12V).
TSM112 incorporates all the necessary functions
for Housekeeping features which allow safe oper-
ation in all conditions, and very high system inte-
gration.
TSM112 integrates a precise voltage reference.
