However, in this world, nothing is perfect. Product is in design stage Target: Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance. Don’t worry that it’s datashert the LMthey’re interchangeable as far as a basic voltage regulator goes.
If this is a concern, or if you simply want to be more power-efficient, you could use a switching regulator to create the 5V, then use your LD to convert 5V to 3. Now this IC has a datasheet here.
My questions are as follows: These regulators try xatasheet maintain their reference voltage your Vr usually about 1. Sign up using Email and Password. LM followed by LD I know at some point when the Vin drops too low there will be now conversion but using these values above datashet I be able to convert say 9V,12V or even 15V to 3.
I am building a circuit that will run off the 12V battery in a bus. I have some off the shelf power regulator boards that use the LM but have a very large electrolytic cap uF on the input and another electrolytic cap 10uF on the output.
My questions are as follows:. One other question with the adjustable voltage regulators the input voltage can range from 15V downwards?

Maybe you have the 1. Spehro Pefhany k 4 That’s a reasonable approximation a lot of the time. Thank you very much for your help. Please contact our sales support for information on specific devices. Is it OK to skip the 0. If the input voltage is too low, the device will be unable to regulate the output, and the output voltage will drop, probably keeping 1.
I’m starting to think datwsheet maybe providing 3. The datasheet states that this is such a small numbers the error it introduces can be safely ignored.

Could I have missed something here? It’s probably worth the extra part to avoid using a tantalum.
General terms and conditions. I did a calculation based on the sparkfun datasheet and I got a value for R2 of 0.
They can all be ceramics including the 10uFhowever you would need to put a series resistor on the 10uF in accordance with datasheet ESR limits.
