Frequently asked questions
What is the price of L7818CV 18V 1.5A Positive Voltage Regulator - STMicroelectronics in Egypt?
L7818CV 18V 1.5A Positive Voltage Regulator - STMicroelectronics currently costs between 8 and 9.5 EGP across 2 offers in Egypt.
Where can I buy L7818CV 18V 1.5A Positive Voltage Regulator - STMicroelectronics in Egypt?
L7818CV 18V 1.5A Positive Voltage Regulator - STMicroelectronics is available from Makers Electronics and RAM Electronics. Compare the offers above to find the best price.
Which capacitors should I add to the L7818CV?
Place a 0.33 µF capacitor close to the input pin and a 0.1 µF capacitor at the output, as shown in the typical application circuit of the datasheet. A larger output capacitor improves response to sudden load changes.
Does the L7818CV need a heatsink?
At 1.5 A, the power lost in the regulator is (Vin − 18 V) × I. If the input is much higher than 18 V, mount it on a heatsink, since the TO-220 package sheds heat through its metal tab.
