A stable DC power source is essential for supplying an electronic circuit or device with a consistent voltage over time. This type of power source is known as a DC Power Supply.

For instance, a 12V battery can provide stable voltage and current for a circuit over a short period, but its voltage and current will decrease over time. Therefore, a battery alone does not meet the long-term stability requirements of a DC power supply.
