ponents. Operating over an input voltage range of 3V to
40V, the LTM8068 supports an output voltage range of
2.5V to 18V, set by a single resistor. There is also a linear
post regulator whose output voltage is adjustable from
1.2V to 18V as set by a single resistor. Only output and
input capacitors are needed to finish the design.
