Difference between Regulated and Unregulated
Power Supplies in Laptop Desktop Power Adapter
In a general sense, a power supply is any device
that supplies energy to an electrical circuit.
Taken this away, batteries are power suppliers
for flashlights and power plants are power
supplies for the electrical grid. Similarly,
laptop desktop power adapter supplies power to
the computers. But thats not usually what we
have in mind when we talk about laptop desktop
power supplies. Usually, we use power supply to
indicate a circuit or a device that adapts
available power to the specific needs of one
device or set of similar devices. In most of the
settings, the available power, or input power, is
AC, and the output power is DC. The laptop
desktop power adapter is converting AC supply
into DC power supply because these electronic
devices are running on DC power supply units in
general.

Regulated Power Supplies in Laptop Desktop Power
Adapter
Regulated power supplies have voltage regulators
on their output. The regulator ensures the output
voltage will always stay at the rated value of
the power supply, regardless of the current that
the device is consuming. This works as long as
the device is not drawing more than the rated
current of the power supply. In fancy electrical
terms, a regulated power supply in laptop desktop
power adapter provides a constant output voltage,
independent of the output current. A regulated
power supply with multiple regulators can offer
multiple output voltages for operating different
devices.

Unregulated Power Supplies in Laptop Desktop
Power Adapter
The voltage of an unregulated power supply is not
regulated. Unregulated power supplies are
designed to produce a certain voltage at a
particular current. That is to use the fancy
electrical terms again, unregulated power
supplies in laptop desktop power adapter provide
a constant amount of power. The output voltage
will decrease as the output current increases,
and vice versa thus, an unregulated power supply
in laptop desktop power adapter should always be
matched as closely as possible to the voltage and
current requirements of the device it is
powering. Unregulated power supplies by their
nature dont produce a clean voltage. Without a
regulator to stabilize the output voltage, any
change in input voltage will be reflected on the
output voltage.

So which is the better choice? It depends on your
needs. Unregulated laptop desktop power adapter
for power supply are less expensive but can only
supply power as clean as the available input
power. If you are powering equipment with
sensitive electronics like laptops, clean power
is an absolute requirement. If you need a laptop
desktop power adapter for power supply that can
offer multiple DC output voltages, then one
regulated power supply with multiple outputs will
be a better option than multiple supplies with
single outputs. Get in touch with us at
