7818 Voltage Regulator Fixed Positive 18V Linear IC L7818CV

  • RM0.95

  • Ex Tax: RM0.90
  • Product Code: 7818
  • Availability: In Stock

7818 is a 18V Voltage Regulator that restricts the voltage output to 18V and draws 18V regulated power supply to provides a convenient power source for most TTL components.

A series of 78XX voltage regulators (as known as L78xx, LM78xx, MC78xx...), the xx is replaced with two digits, indicating the output voltage (for example, the 7805 has a 5-volt output, while the 7812 produces 12 volts).

 

Applications

  • Circuits requiring steady 18v supply
  • Protection for devices having specific voltage sensitivity
  • DIY projects requiring specific voltage from an existing higher/ varying voltage supply

 

Features

  • Fixed 18V voltage regulators
  • Thermal overload protection
  • Short circuit protection
  • Output transition SOA protection
  • Heatsink is required *

Linear regulator like 7818 has performance issues with respect to battery life and Power loss. If you are looking for an alternative for 7818 with better efficiency and less power loss, then we would recommend a DC Buck Switching voltage regulator

Buck converters may be preferred over 78xx regulators because they are more efficient and do not require heat sinks, but they are more expensive.
