NCP786A
Wide Input Voltage Range
10ꢀmA Ultra-Low Iq, High
PSRR Linear Regulator with
Adjustable Output Voltage
www.onsemi.com
The NCP786A is 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 10 mA. Ideal for high input voltage applications such
as industrial and home metering, home appliances. The NCP786A
family offers 3% initial accuracy, extremely high−power supply
rejection ratio and ultra−low quiescent current. The NCP786A family
is optimized for high−voltage line and load transients, making them
ideal for harsh environment applications. The output voltage can be set
by resistor divider in range from 1.27 V up to 15 V. DFN6 5x6 Pb−free
package with high allowable power dissipation keep small footprint at
space sensitive applications.

Layout Recommendations
Input Decoupling (C1)
A 4.7 mF capacitor either ceramic or electrolytic is
recommended and should be connected close to the input pin
of NCP786A. Higher value 4.7 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. The capacitor 2.2 mF or 1 mF could be acceptable
for DC input voltage or AC input voltage 235 V 20%.
There must be assured minimum Input Voltage more than
55 V at input pin of NCP786A regulator in order to keep
stable desired output voltage with guaranteed parameters.
Please be sure that the V and GND lines are sufficiently
IN
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.
Thermal
As power across the NCP786A 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 NCP786A has good
thermal conductivity through the PCB, the junction
temperature will be relatively low with high power
dissipation applications.
Output Decoupling (C2)
The NCP786A Regulator 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 2.2 mF. The
regulator accepts ceramic chip capacitors as well as
tantalum devices or low ESR electrolytic capacitors. Larger
values improve noise rejection and especially load transient
response.

Output Voltage
The output voltage can be set by using a resistor divider
as shown in Figure 1 in range from 1.275 V up to 15 V. The
appropriate resistor divider can be found by solving the
equation below.
The recommended current through the resistor divider is
from 1 mA to 3 mA in order to keep negligible ADJ pin
consumption. In this case we can simplify Equation 1 to:
