external noise reduction capacitor. Unlike other low noise
regulators which require an external capacitor and have slow
startup times, the NCV8603 operates without a noise
reduction capacitor, has a typical 15 ms start up delay and
achieves a 50 mV

Enable Operation
threshold limits are covered in the electrical characteristics
table in this data sheet. The turn−on/turn−off transient
voltage being supplied to the enable pin should exceed a
slew rate of 10 mV/ms to ensure correct operation. If the
enable function is not to be used then the pin should be
connected to V
Thermal
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and the ambient temperature
affect the rate of junction temperature rise for the part. When
the NCV8603 has good thermal conductivity through the

high, there is a chance to pick up noise or cause the regulator
to malfunction. Place external components, especially the
output capacitor, as close as possible to the NCV8603, and
make traces as short as possible.
