Rangkaian Power Supplay
Electronic devices should be powered by direct current supply DC
(direct current) which is stable in order to work properly. The battery
or batteries is a source of DC power supply is best. But for
applications that require greater power supply, the source of the
battery is not enough. Sources of power supply is a source of
alternating AC...

1.25V-15.19V Regulator/Adaptor Variabel Digital
Rangkaian Regulator/Adaptor Variabel DigitalThis is a series regulator
with variable output from the digital 1.25V to 15.19V The first section
of the circuit comprises a digital up-down counter built around IC1, a
quad 2-input NAND Schmitt trigger (IC CD4093), followed by IC2, a
binary up-down counter (CD4029 IC). Two gates of IC CD4093...

Rangkaian USB Power Boster (USB Adaptor )
USB Power Boster (USB Adaptor )USB can be configured for connecting
several peripheral devices to a single PC, Since a PC can supply only a
limited power to the external devices connected through its USB port,
when too many devices are connected simultaneously, there is a
possibility of power shortage, Therefore an external power source...

Adaptor 12 volt menggunakan 2n3055
Rangkaian Adaptor 12 volt 2n3055This adapter circuit can deliver up to
3A at 12V output voltage. The circuit can be employed on occasions when
a current of more that 3A is demanded for regulator. IC regulators of
such high current rating are pretty hard to find.The transformer T1
steps down mains voltage, to 12rms & the rectifier bridge...
+12Volt|-12Volt Dual Regulator Power Supplay
This is of a dual regulated that provides +12V and -12V from the AC
mains. A regulator like this is a very essential tool on the work bench
of an electronic hobbyist.Transformer T1 steps down the AC mains
voltage and diodes D1, D2, D3 and D4 does the job of rectification.
Capacitors C1 and C2 does of filtering.C3, C4, C7and C8 are
decoupling...

Rangkaian +5V Switching regulator
Rangkaian +5V Switching regulator used LM2575-5.0. You can make the
stable voltage by using the 3 terminal regulator like LM317. However,
because the output electric current and the inputted electric current
are the same approximately, the difference between the input electric
power (The input voltage x The input electric current) and the...

Rangkaian Regulator menggunakan Op-Amp
Regulator is a series of regulations or the voltage output from power
so that a portion darinaik effects or voltage drop in net does not
affect the voltage ration power to be so stable.Regular circuit of
regulators have been good if the ripple voltage is small, but there is
a problem of stability. If the voltage PLN rise /down, then the...

ADAPTOR 12 VOLT 20 AMPERE
Now it should not have to wrestle again seek op-amp, transistor and
other components to realize a massive circuit of regulators, because
the circuit of this kind have been packed into a fixed voltage
regulator IC. Currently, many components known as the 78XX series fixed
positive voltage regulator and the 79XX series is a voltage regulator...
