Vintage Motorola MC1469R Positive Voltage Regulator in Metal TO-66 Can with Gold Legs
This regulator supports legacy power-supply and analog circuits that rely on multi-lead metal packages rather than modern three-terminal layouts. It provides a defined positive output from a higher DC rail in equipment built around classic adjustable linear regulation, and a single regulator/output topology variant ensures clarity across older schematics. A rail/supply synonym helps match vintage documentation.

Product Overview
The Motorola MC1469R is a positive adjustable linear regulator from the MC1469/MC1569 family, supplied in a TO-66-style metal package with multiple gold-plated leads. It integrates a reference, pass device, and error amplifier to generate a regulated positive rail. Its mechanical format and multi-lead pinout differ from modern regulators, making original-form components important for accurate restoration and repair of classic instrumentation and power assemblies.

Frequently Asked Questions
Is the MC1469R a drop-in replacement for modern three-terminal regulators?
No. Its multi-lead format and compensation expectations differ from devices like the 78xx series, so using the original pin mapping is important.
What defines the “R” package style?
The R suffix denotes a metal can form with multiple extended leads, mechanically distinct from plastic DIP or TO-220 packages.
Does this regulator include an internal reference?
Yes. The MC1469 family incorporates a reference and error amplifier for adjustable positive output regulation.
Why is maintaining the original metal case important in restorations?
The case was often tied to a defined potential and mechanically integrated into the chassis or heatsink, influencing grounding and thermal paths.
Use this regulator to restore analog control electronics by establishing regulated positive rails, drawing on its multi-lead pin mapping and metal-case mounting when fitting it to your existing heatsink.
