Some regulators get unhappy if the input is not powered while power is applied to the output from some other source. Ame117 enter 5 or 9 numbers for the ZIP Code.

See the seller’s listing for full details. This item will be shipped through the Global Shipping Program and includes international tracking. Tantalum capacitors on the input from a supply that is not current limited are a fire hazard and such a design would never get UL approval.

Interest will be charged to your account from the purchase date if the balance is not paid in full within 6 months. The item you’ve selected was not added to your cart. What I personally do for my power supply is something like this: The adjustable devices are floating voltage regulators. I would just like some pointers. Add to cart – Best Offer: And he’s using lipo batteries for power, definitely not a tant on input.

D2 is only needed if you fear the power may be connected backwards C1 output cap is 10uF ceramic, rated a bit above the expected voltage ceramics don’t explode like tants when you exceed voltage spec, so you don’t have to derate them C2 input cap is uf ceramic.

Make Offer – Loading Seller information satisfyelectronics This amount is subject to change until you make payment.

If you are bound and determined to use a LiPo, you really should incorporate some type of fusing between the battery and the regulator. See all condition definitions – opens in a new window or tab But I cant find them on the commercial sites like ebay. Mouse over to Zoom – Click to enlarge.

But as The Photon explained the difference is somewhat academic, because the adjustable one simply sets its output [typically] 1. Please note the delivery estimate is greater than 6 business days. Look at Fig 2 in the datasheet. To be or not to be? Because I’m designing my own circuit well made and gonna cover it with heat resist film there no gonna be any possible ways to short my circuit by mistake, only if i really need to short it So in this case as you described the components thanks for that a lot I’m gonna use the regulator you suggested me ZLDgonna use Diode D2 to be sure no one will plug by mistake the battery in the other way, about the D1 it’s not really needed in my case and about the C3 when you mean if I expect lots of sharp changes in current I maybe add extra one to be sure and safe.

What is the purpose of the diode on the input? Would be that setup ok? They also don’t seem to mind mind if the circuit is powered while the regulator input is not.

The AMS datasheet states that you need to use tants. For the fixed output devices R1 and R2 are included within the mas117 and the ground current Ignd, ranges from 3. They develop and maintain the nominal 1. Sellers set the item’s declared value and must comply with customs declaration laws.


In these cases, put a diode from the output to the input with band towards output, ofc.

Domino60 on Aug 19, If you think the input might be connected backwards, you’d want a diode to protect against that About the battery and the voltage drop that will not be a problem, i will use 2S Li-Po or Li-Ion they have a lot of current, 1s 3. Since the adjust pin current, Iadj, is significantly lower and constant with respect to the programmed load current, it generates a small output voltage error that can usually be ignored.

C3 – optional additional output cap – normally not needed, but might be – if you expect lots of sharp changes in current, and you care about a little ripple, think about this. They indicate that 10uf is sufficient for most applications, as well.

BUt I am still ajs117 as to whther this is actually adjustable since in the datasheet,AMS on page 2it says, 1. See terms – opens in a new window or tab. Sell now – Have one to sell?

I’m gonna use AMS 3. The ADJ pin is carefully controlled to be almost exactly asm117. Select a valid country. The second cap in parallel with it assuming it’s actually in that part of the board, not one of the 0. Refer to eBay Return policy for more details.

On figure 2, they have a diagram for R1,R2.
