NCV8509 Series
Sequenced Linear
Dual-Voltage Regulator
The NCV8509 Series are dual voltage regulators whose output
voltages power up in such a manner as to protect the integrity of
modern day microcontroller I/O and ESD input structures. Newer
generation microcontrollers require two power supplies. One voltage
is used for powering the core, while the other powers the I/O.
