WS78L05 is 5V, Voltage Regulator. Voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage.

It does this by adjusting the output voltage so that it remains within a specified range.

This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.

This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of
applications. These applications include on-card regulation for elimination of noise and distribution
problems associated with single-point regulation.

In addition, they can be used with power-pass elements to make high-current voltage regulators.
One of these regulators can deliver up to 100 mA of output current.
