[LD] Voltage Regulators | circuitholic

The datasheet states that this is such a small numbers the error it introduces can be safely ignored. One other question with the adjustable voltage regulators the input voltage can range from 15V downwards? However, in this world, nothing is perfect. Put it closer to the LM So I’m getting 5V from Arduino and turning it into 3.

Sign up using Email and Password. The maths involved isn’t very difficult, but I do find that I’m always fighting a losing battle of what resistors I need vs. Communications Equipment, Computers and Peripherals. Marketing proposal for customer feedback.

It’s saved me hours of time! Regarding the output capacitor requirements of the LM, below is the information from the TI nee National Semiconductor, the original designers datasheet for their LM LD not providing fixed 3.

Selectors Simulators and Models. No availability reported, please contact our Sales office. Concerning fixed versions, are offered the following output voltages: Are you sure you have the 3.

Yes have a look at the datasheet datzsheet. See below on how I calculated the values:. Support Center Video Center.

power – LM followed by LD – Electrical Engineering Stack Exchange

I am just trying to understand whether there are any gotchas in connecting the output of the LM to the input of the LD It tells you precisely how to use just two resistors to set the voltage of the output to whatever it needs to be. Product is in volume production Evaluation: Not Recommended dataheet New Design.

The LM recommends a smaller cap on the output compared to that on the input, whereas the LD Post as a guest Name. Note that a 10uF ceramic capacitor has a negative voltage coefficent as well as a tolerance, so you may wish to use a higher voltage rated part or a higher nominal capacitance part to ensure the 10uF minimum requirement is met, just to be completely safe.

I did a calculation based on the sparkfun datasheet and I got a value for R2 of 0. See below on how I calculated the values: NK Please see the edit above.

Now this IC has a datasheet here. The ST datasheet does not say it is stable with a ceramic part.

LM followed by LD That’s most likely the adjustable version. Product is in volume production 0.
