NCV8509/D

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.
