7812 Voltage Regulator Fixed Positive 12V Linear IC L7812CV

  • RM0.95

  • Ex Tax: RM0.90
  • Product Code: 7812
  • Availability: In Stock

7812 is a 12V Voltage Regulator that restricts the voltage output to 12V and draws 12V regulated power supply. The 7812 is the most common, as its regulated 12-volt supply provides a convenient power source for most TTL components.

7812 is a series of 78XX voltage regulators. For ICs within the family, 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).

Linear regulator like 7812 has performance issues with respect to battery life and Power loss. If you are looking for an alternative for 7812 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.
