If you don’t load the LM sufficiently 5mA or more the output voltage can rise out of regulation- I think that’s clearly stated in the datasheet. However, in this world, nothing is perfect.

Initially I got an output of 2V Product is in design feasibility stage. Getting started with eDesignSuite 5: Product is under characterization. In this case, if the regulator is supplying mA, the input voltage should be at least 1. I’m starting to think that maybe providing 3.

No numbers after a regulator part number is a very good indicator that you have an adjustable version.

I am hoping for additional protection against fluctuations in the 12V supply from the bus battery. I had a look at the datasheet they provide in the product page but it points me to a Fairchild semi conductor datasheet which has a datasheeet application note that looks like this: Sign up using Facebook. Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance.


Getting started with eDesignSuite. Spehro Pefhany k 4 I am just trying to understand whether there are any gotchas in connecting the output of the LM to the input datasneet the LD That’s most likely the adjustable version. I am building a circuit that will run off the 12V battery in a bus.

I am really trying to understand how to use adjustable voltage regulators such as the LD sold by sparkfun. If they are close to each other, perhaps.

Computers and Peripherals Data Center. I need dataasheet supplies – 5V and 3. Which one should I use?


Media Subscription Media Contacts. Distributor Name Region Stock Min. I did a calculation based on the sparkfun datasheet and I got a value for R2 of 0. Partly history of the applications, but the LM actually needs a capacitor on the output with certain characteristics to keep it from oscillating like a banshee.

The LM datasheet recommends a 0. Product is in volume production. Maybe you have the 1. Passerby I can’t say I’m sure, that’s what I asked for at the shop. As for me, the value of the capacitor is decided by the value of the voltage.

It’s probably derived from an older NS datasheet from which the ST part was derived before 10uF ceramic capacitors were widely available. Adjustable and fixed low drop positive voltage regulator. This datasheet is a lot more detailed and on page 24 there is an application note for the adjustable variant.

CharlieHanson 1, 4 Concerning fixed versions, are offered the following output voltages: Bruno 50 1 2 6.

All fair and well so I went over to this online calculator and tried to see how these values work. Sign up using Email and Password. Home Questions Tags Users Unanswered.
