Post as a guest Name. Product is in design feasibility stage. Use a LD calculator if you want to use different value resistors. Email Required, but never shown.

Post as a guest Name. The ST datasheet does not say it is stable with a ceramic part. The power system in a bus and other motor vehicles is pretty dirty, with lots of voltage surges and other electrical noise Does the ohm here refer to ESR of Dataasheet Yes Please refer to the answer 3.

LM followed by LD Please contact our sales support for information on specific devices. Who We Are Management. I know at some point when the Vin drops too low there will be now conversion but using these values above would I be able to convert say 9V,12V or even 15V to 3.

I am just trying to understand whether there are any gotchas in connecting the output of the LM to the input of the LD The adjustable LD is pin to pin compatible with the other standard.

Key Features Low dropout voltage 1 V typ. Selectors Simulators and Models. The LM datasheet recommends a 0. This is the little guy. It is my first question on this site and I’m probably doing something wrong, try to be gentle!

Computers and Peripherals Data Center. With the experiment I have just done I am pretty sure I understand this now.

To make it 3. Going higher dataheet value is usually better with capacitors and those are really common values for an off-mains supply for moderate current.

Buy Direct Add to cart. So datasheet like a series 0. Generally, I datashret one 10uF and one nF as output capacitors for 5V and 3. Yes have a look at the datasheet st. I am building a circuit that will run off the 12V battery in a bus. This datasheet is a lot more detailed and on page 24 there is an application note for the adjustable variant.

TI have wisely updated their datasheet to warn the inexperienced about this pitfall.

It’s probably derived from an older NS datasheet from which the ST part was derived before 10uF ceramic capacitors were widely available.

Concerning fixed versions, are offered the following output voltages: No numbers after a regulator part number is a very good indicator that you have an adjustable version. Product is in volume production only to support customers ongoing production.

I do however remember seeing such a spec in a similar LDO manufactured by an unknown company.
