Noise Decoupling
external noise reduction capacitor. Unlike other low noise
regulators which require an external capacitor and have slow
startup times, the NCP600 operates without a noise
reduction capacitor, has a typical 15 ms start up delay and
achieves a 50 mV
100 kHz.
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
Output Voltage Adjust
(Figure 4) to 4 times (Figure 5) the typical 1.250 V
regulation voltage via the use of resistors between the output
and the ADJ input. The output voltage and resistors are
chosen using Equation 1 and Equation 2.
Choose R2 arbitrarily to minimize errors due to the bias
current and to minimize noise contribution to the output
voltage. Use Equation 2 to find the required value for R1.
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 NCP600 has good thermal conductivity through the
PCB, the junction temperature will be relatively low with
high power applications. The maximum dissipation the
NCP600 can handle is given by:
The NCP600 is a low noise regulator and needs no

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 NCP600, and
make traces as short as possible.
