Lm7805 5v Voltage Regulator

The current rating and the secondary voltage of the transformer is a crucial.

Lm7805 5v voltage regulator.

5 7cm 2 3cm 2. 7805 is 5v positive voltage regulator. It is an ic in the 78xx family of linear voltage regulators that produce a regulated 5v as output. 7805 ic is an iconic regulator ic that finds its application in most of the projects.

The name 7805 signifies two meaning 78 means that it is a positive voltage regulator and 05 means that it provides 5v as output. Selecting a suitable transformer is of great importance. As we require a 5v we need lm7805 voltage regulator ic. Current rating i c 1a.

A brief note on 7805 voltage regulator. Input voltage range 7v 35v. The 7805 of three terminal regulators is available with several fixed output voltages making them useful in a wide range of applications. 5v from arduino which says 5v max 40ma.

Here comes the 7805 voltage regulator ic to the rescue. 7805 voltage regulator ic says 5v up to 1a and 3. To which say pir is attached which works at 5 to 12 v is different current will burn my pir sensor or it will just work fine and use it s required current.
