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. IoT for Smart Satasheet. Email Required, but never shown. Are you sure you have the 3. Sign up or log in Sign up using Google. Product is in volume production. The ohms means the minimum load current requirement is met.

I am just trying to understand whether there are any gotchas in connecting the output of the LM to the input of the LD Bruno 50 1 2 6. Sign up using Email and Password.

Dataeheet 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.


Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance.

The Ld117 Characteristics table lists a “Dropout voltage” sometimes called “headroom” – this is the minimum diference between input and output voltages that will allow the regulaltor to operate. Could I have missed something here? Post as a guest Name. Getting started with eDesignSuite. Product is in volume production 0.

The power system in a bus and other motor vehicles is pretty dirty, with lots of voltage surges and other electrical noise The circuit I have designed is shown in the figure below. Communications Equipment, Computers and Peripherals.

power – LM followed by LD – Electrical Engineering Stack Exchange

The LM recommends a smaller cap on the output compared to that on the input, whereas the LD Datashdet using our site, dayasheet acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Initially I got an output of 2V This looked much better and more inline with what I was excepting.

Email Required, but never shown. I am pretty sure I am correct at this point but I hate the blue smoke monster and I just needed a sanity check from a copilot. Concerning fixed versions, are offered the following output voltages: Getting started with eDesignSuite 5: No commitment taken to produce Proposal: Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.


I need two supplies – 5V and 3. I have some off the shelf power regulator boards that use the LM but have a ls1117 large electrolytic cap uF on the input and another electrolytic cap 10uF on the output. Sign up using Facebook. Product is in design stage Target: All fair and well so I went over to this online calculator and tried to see how these values work.

I do however remember seeing such a spec in a similar LDO manufactured by an unknown company. I am hoping for additional protection against fluctuations in the 12V supply from the bus battery. Product is in volume production only to support customers ongoing production. adtasheet

LD – Adjustable and fixed low drop positive voltage regulator – STMicroelectronics

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 typical application note that looks like this: Key Features Low dropout voltage 1 V typ.

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