5v power supplies digital power supplies.
A typical power supply unit consists of the following.
A regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure.
The switch mode power supply circuit with very low output power of less than 100w watts is commonly a type of fly back converter smps it is very simple low cost circuit compared to other smps circuits.
Hence it is used for low power applications.
The circuit drawn pertains to a regular industrial ups uninterruptible power supply which shows how the batteries take control during an outage in electrical supply or variation beyond the normal limits of the voltage line without disruption on the operation providing a steady regulated output 5 volts by lm7805 and an unregulated supply 12 volts.
