www.onsemi.com
MARKING
The NCP785 is a high−performance linear regulator, offering a very
wide operating input voltage range of up to 450 V DC, with an output
current of up to 5 mA.
Ideal for high input voltage applications such as industrial and home
metering, home appliances. The NCP785 family offers 5% initial
accuracy, extremely high−power supply rejection ratio and ultra−low
quiescent current. The NCP785 family is optimized for high−voltage
line and load transients, making them ideal for harsh environment
applications.
The NCP785 is offered in fixed output voltage options 3.3 V and
5.0 V.
SOT−223 and SOT−89 packages offer good thermal performance
and help to minimize the overall solution size.

recommended and should be connected close to the input pin
of NCP785. Higher value 2.2 mF is necessary to keep the
input voltage above the required minimum input voltage at
full load for AC voltage as low as 85 V with half wave
rectifier.
wide. When the impedance of these lines is high, there is a
chance to pick up noise or to cause the malfunction of
regulator.
Set external components, especially the output capacitor,
as close as possible to the circuit, and make leads as short as
possible.
Output Decoupling (C2)
The NCP785 is a stable Regulator and does not require
any specific Equivalent Series Resistance (ESR). Thus
capacitors exhibiting ESRs ranging from a few mW up to
0.5 W can be used safely. The minimum decoupling value is
22 mF. The regulator accepts ceramic chip capacitors as well
as tantalum devices or low ESR electrolytic capacitors.
Larger values improve noise rejection and load transient
response.
Thermal
As power across the NCP785 increases, it might become
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design layout and used package. Mounting pad
configuration on the PCB, the board material, and also the
ambient temperature affect the rate of temperature rise for
the part. This is stating that when the NCP785 has good
thermal conductivity through the PCB, the junction
temperature will be relatively low with high power
dissipation applications.
