LM79LM63
LM79LM63 is not a standard, widely documented regulator in major manufacturers’ public catalogs. It may be a misprint, a vendor-specific internal code, or a cross-reference error that combines the LM79xx family naming with another part number. If you have encountered this designation in a datasheet or bill of materials, the safest course is to verify with the supplier or obtain the official datasheet for that exact device. If the designation is intended to refer to a member of the LM79xx family, it would denote a three-terminal fixed negative voltage regulator.
The LM79xx family comprises fixed negative regulators used to generate precise negative supply voltages in electronic
Operation and requirements: LM79xx regulators generally require input and output capacitors for stability and transient response.
Pinout and packaging: In common TO-220 packages, pins are arranged for three-terminal operation, with the exact
