Three-terminal integrated voltage regulator circuit 78L05 description:
The 78L05 is a three-terminal voltage regulator. It can be used as a replacement for a Zener diode/resistor combination. It offers two orders of magnitude of improved product impedance and low static current. These features make the regulator an excellent solution for providing noise interference mitigation in on-board or card-mounted voltage stabilization. The 78L05 provides a superior stereo power solution for computer motherboards.
