The EZ158X is a low dropout regulator designed to power
low voltage microcontrollers, graphics ICs, sound cards
etc.
The dropout voltage is minimized by utilizing a separate
input voltage, V
1.3V. The 2.5V (for example) power for the load can be
derived from a 3.3V system supply. Since the efficiency
of a linear regulator is the ratio of the output to the input
voltage, heat dissipation is reduced by using a 3.3V input
(versus a 5V one), thereby lowering heatsink and cooling

, which should exceed V

fan costs. For lower current applications, the heatsink
might be eliminated altogether. For a load of 7A at 2.5V,
the regulator would dissipate 17.5W when converting from
5V, but only 5.6W from a 3.3V input.
Remote Kelvin sensing of the output voltage can be
achieved by connecting the sense pin to the output at
the load. Remote sensing will reduce errors associated
with resistive trace losses between regulator and
processor.
