Motorola MC1463R Negative Regulator in Metal TO-66 Package with Gold Legs
This adjustable negative regulator supports legacy analog and instrumentation circuits that rely on multi-lead metal can devices. Its role in producing stable negative rails makes it useful for repairs and period-correct builds, and a single regulator/supply variant ensures clarity in older schematics. An analog/linears synonym helps match varied documentation.

Product Overview
The Motorola MC1463R is a vintage adjustable negative linear regulator in a TO-66 metal package with gold-plated leads. It was used to establish regulated negative rails in instrumentation, analog audio circuits, and mixed-signal assemblies. Its multi-lead layout reflects era-specific design practices that differ from modern three-terminal regulators, making original-form replacements valuable for accurate restorations.

Frequently Asked Questions
Is the MC1463R directly interchangeable with modern three-terminal regulators?
No. Its multi-lead configuration and case-grounding practices differ from modern devices, so original-coordinate replacement is recommended.
Does the TO-66 case affect installation?
Yes. The regulator’s metal case was typically tied to ground in original designs, allowing direct mounting to grounded heatsinks.
What voltage range can this family support?
The MC1463 family was designed for adjustable negative rails spanning several tens of volts when set by external components.
Why is gold-lead Motorola stock valued?
Gold wiring and lead finishes were common in certain Motorola eras and remain desirable for restoration accuracy and long-term stability.
Use this regulator to rebuild legacy analog instruments by generating regulated negative rails, drawing on its metal-case grounding and multi-lead control while mounting it to your existing grounded heatsink.
