Overview
The MC79L05ACLPM, produced by Texas Instruments, is a fixed negative-voltage integrated-circuit voltage regulator. This device is part of the MC79L series, designed to provide stable negative voltage outputs for a wide range of applications. It is particularly useful for on-card regulation, eliminating noise and distribution problems associated with single-point regulation. The regulator can also be used to control series pass elements in high-current voltage-regulator circuits.
