Email Required, but never shown. Sir i made a voltage regulator using dataasheet for powering my microcontroller but my chip isnt working Plz tell me where i m wrong. So the 20V delivers 20W, while the load only consumes 12W. I have given bellow a schematic diagram in which two ICs are attached together and both of them are carrying almost equal load. The xx in 78xx indicates the output voltage it provides. This cf circuit will provide 12V and approximately 2A current.

The current to your load flows through the regulator and is the same current as will be drawn from the input voltage. Comment from Sagar Awachat Time April 11, at 4: The heart of the IC is a transistor Q16 that controls the current between the input and output and thus controlling the output voltage.


Thanks to the transistor like shape of which makes it easy to mount on a heatsink plate. Dean 4, 22 57 Premium freight is not available on oversized or bulky items. This difference between the input and output voltage is released as heat. Peter Mortensen 1, 3 14 A voltage regulator may use a simple feed-forward design or may include negative feedback. This is dstasheet snapshot of page 8: Both resistors should be minimum 15 Watt or above.

daatasheet Comment from Sanjeev Time October 29, at If you need more power then there are a few ways to do so. Sign up using Facebook. So twice the energy, that is actually utilized is wasted.

If you hold upside down pins up and the IC number is facing you then the left pin will be the voltage regulator output, the center pin will be ground and the right pin will be the voltage datasheer pin. Be the first to know about our newest products, specials and promotions: On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. A resource for professional design engineers. More tutorials available at learning resources.


Instead, the entire chip becomes the feedback loop. This amplified signal controls the output transistor through Q Capacitors will be beneficial in this case as they are good at maximizing voltage regulation.

If we look further we can see two values for line regulation; it appears that this is best if the input voltage is at least 16V. Pleased sir kindly anwser to my mail adelusioluwatosin01 gmail.

The two capacitors are not necessarily required and can be omitted datasgeet you are not concerned about line noise. Mail will not be published required. The maximum dropout voltage Vd is 2. The circuit in purple provides protection against overheating Q13excessive input voltage Q19 and excessive output current Q We do not dstasheet insure unless you specify it during the checkout.

You want to transfer, water, for example, from one side to the other.
