... 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. ...
