Low Dropout Linear
Regulator with Watchdog,
Wake Up, RESET, and
ENABLE
The NCV8518A device is a precision micropower voltage regulator.
It has a fixed output voltage of 5.0 V and regulates within ±2%. It is
suitable for use in all automotive environments and contains all the
required functions to control a microprocessor. This device has low
dropout voltage and low quiescent current. It includes a watchdog
timer, adjustable reset, wake up and enable function. Also
encompassed in this device are safety features such as thermal
shutdown and short circuit protection. It is capable of handling up to
45 V transients.
