KIA SEMICONDUCTORS THREE TERMINAL POSITIVE VOLTAGE REGULATORS 5V.

The 78L05 is a commonly used linear voltage regulator integrated circuit (IC). It is part of the 78xx series of voltage regulators, which are designed to provide a stable and regulated output voltage. Specifically, the 78L05 is a positive voltage regulator that produces a fixed output voltage of +5 volts.

 

 

The "78" in the name refers to the original series introduced by Texas Instruments, and the "L" indicates a low current variant. The "05" denotes the specific output voltage of +5 volts. The 78L05 is also available in other output voltage variants, such as 78L06 (+6 volts) and 78L08 (+8 volts), with each variant having a different number at the end to represent its output voltage.
