Overview
The MC79L05ACLP is a fixed negative-voltage integrated-circuit voltage regulator produced by Texas Instruments. This regulator is part of the MC79L00 series and is designed for a wide range of applications, including on-card regulation to eliminate noise and distribution problems associated with single-point regulation. It can also be used to control series pass elements in high-current voltage-regulator circuits. The MC79L05ACLP is known for its simplicity and reliability, requiring no external components and featuring internal thermal-overload protection and short-circuit current limiting.
