DESCRIPTION
Lot of 4 new old stock Fairchild Semiconductor µA7812UC 3-terminal positive 12V voltage regulators in TO-220 packages. Each is marked "UA7812UC," "F 8235," and "KOREA." Date code 8235 places manufacture in 1982. Never installed. Leads show light storage discoloration, as pictured.
The µA7812 is Fairchild's original part number in the industry-standard 7812 12V regulator family.

Features:
Fixed 12V positive output
1A output current with adequate heatsinking
35V maximum input voltage
Typical 2V dropout at 1A
Internal thermal shutdown and short-circuit current limiting

Output transistor safe-area protection
TO-220 package with metal mounting tab
Original Fairchild manufacture, 1982 date code
4 pieces

Compatibility:
Direct replacement for µA7812, UA7812UC, LM7812, MC7812, and L7812 12V TO-220 positive regulators. Standard 78xx TO-220 pinout: Input, Common, Output, with the tab connected to Common.

Q&A
Q: What is the UA7812UC?
A: A Fairchild 12V, 1A three-terminal positive voltage regulator in a TO-220 package.
Q: What replaces a UA7812UC?
A: These are direct replacements. Any 7812-type 12V TO-220 positive regulator (LM7812, MC7812, L7812) fits the same position.
Q: What input voltage does it need?
A: About 2V above the 12V output at 1A, up to a 35V maximum.
Q: How old are these parts?
A: Date code 8235, which places manufacture in 1982.
