Signal Description

On-Chip Linear Regulator
The MCF5253 includes an on-chip linear regulator. This regulator provides an 1.2 V output which is
intended to be used to power the MCF5253 core. Three pins are associated with this function; LININ,
LINOUT, and LINGND. Typically, LININ would be fed by the I/O (PAD) supply (3.3 V) with separate
filtering recommended to provide some isolation between the I/O and the core.
In portable solutions, this linear regulator may not be efficient enough. In this case, we would expect the
1.2 V supply to be generated externally, possibly by a highly efficient DC-DC convertor.
If not used, leave pins unconnected.
