NCV8509: Sequenced Linear Dual-Voltage Regulator

Product Description
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.
Power up sequencing of these dual voltages is crucial to ensure the integrity of the microprocessor.
