ITEM SPECIFICS
Brand: National Semiconductor
MPN: LM340KC-5.0
Series: LM340
Type: Fixed Positive Linear Voltage Regulator
Output Voltage: +5 V DC
Package: TO-3 Metal Can
Mounting Type: Through Hole
Number of Leads: 2
Additional Marking: 7805CK
Quantity: 1
Condition: New
DESCRIPTION
National Semiconductor LM340KC-5.0 fixed positive voltage regulator in a TO-3 metal-can package. This regulator provides a nominal +5 V DC output. The photographed component carries the National Semiconductor logo and LM340KC, -5.0, and 7805CK markings.
Features:
Fixed +5 V DC output
Positive linear voltage regulation
TO-3 metal-can package
Internal current limiting
Thermal shutdown protection
Safe-area compensation
Compatibility:
For circuits requiring the LM340KC-5.0 regulator and its documented electrical and thermal characteristics. Confirm the input voltage, terminal connections, output-current requirements, and heat-sink arrangement before installation. Other LM340 voltage options and package styles require separate verification.
Q&A:
Is this a positive or negative regulator?
It is a positive regulator with a nominal +5 V DC output. The -5.0 portion identifies the output-voltage option.
Does this convert AC directly to regulated DC?
No. It requires a suitable DC input. Any required rectification and filtering must be provided by the surrounding circuit.
Does it require a heat sink?
Heat-sink requirements depend on input voltage, output current, ambient temperature, and power dissipation. Adequate cooling is required to remain within the manufacturer’s thermal limits.
How many components are included?
One LM340KC-5.0 regulator.
Troubleshooting:
For inadequate output regulation, the manufacturer’s application guidance calls for sufficient input-voltage headroom and adequate heat sinking. Input bypassing may be needed when the regulator is located far from the power-supply filter capacitor. Follow the datasheet’s connection and thermal requirements.
