Frequently asked questions
What is the price of LM309K 5V 1A Positive Voltage Regulator TO-3 Steel in Egypt?
LM309K 5V 1A Positive Voltage Regulator TO-3 Steel currently costs 80 EGP in Egypt.
Where can I buy LM309K 5V 1A Positive Voltage Regulator TO-3 Steel in Egypt?
LM309K 5V 1A Positive Voltage Regulator TO-3 Steel is available from Makers Electronics. Compare the offers above to find the best price.
What input voltage does the LM309K need?
The input must stay several volts above 5 V to account for the dropout specified in the datasheet. An input of about 7 V to 9 V is a common choice. Place input and output capacitors close to the regulator as the datasheet recommends.
Does the LM309K need a heatsink?
At higher loads, yes. A linear regulator dissipates (Vin − 5 V) × load current as heat, so a large voltage drop with high current requires a heatsink on the metal TO-3 case.
