GENERAL DESCRIPTION
The CM8501C is a low cost switching regulator designed to
provide a desired output voltage or termination voltage for
various applications by converting voltage supplies ranging
from 2.0V to 4.5V. The CM8501C can be implemented to
produce regulated output voltages in two different modes. In
the default mode, when the VIN/2 pin is open, the output
voltage is 50% of the VCCQ. The CM8501C can also be used
to produce various user-defined voltages by forcing a voltage
on the VIN/2 pin. In this case, the output voltage follows the
VIN/2 pin input voltage. The regulated output voltage of
CM8501C is internally set to be 50% of the applied VCCQ.
The switching regulator is capable of sourcing or sinking up to
1.5A of current while regulating an output V
TT
voltage to
within 3% or less.
The CM8501C provides low profile 8-pin PSOP package to
save system space.
