D2Pak, LDO 5 volt, 3.0 amp regulator with control pin?

[Badass45]

Hey Hoog,

Any idea when you are going to get more of these in?
I like the smaller size.

If no time soon, could you send me a link of where I might get some.

I'd love to but ON Semi discontinued them and haven't announced a replacement yet.. I've got some peeps looking for excess stock but haven't found anything yet.

As a potential replacement, consider the LD29300P2M33R from STMicro. The P2PAK package is approximately the same size as D2PAK.

For a really small regulator with control, try the LK112M50TR in SOT23.

Specs don't look up to par on either one of those.
Thanks for the info though.

No wonder I can't find anything that is a compatible part. They don't seem to make one anywhere.

What specs are you looking at? They're pretty damn close.

The LD29300 part has a 1.5V dropout compared to 1.3 on the ON semi part, but it's also rated for 5A vs 3A for the ON. Both are 5V regs with 1% accuracy and control pins in almost identical packages. For mod purposes, they're essentially interchangeable. The LK112 was just thrown in there as an example of a really small part that will also get the job done.

If you're looking for a direct replacement for the NCP5666 from ON, Mouser lists the NCP5667 as a "new" part, so that may be the intended replacement.

The spec sheet (LD29300P2M33R datasheet, Pinout ,application circuits 3A, Very Low Drop Voltage Regulators) for the LD29300P2M33R says it is only 3.3 volt out.

The NCP5667 doesn't show a control pin.

I may be wrong as I am a motor control person not an electronics expert. Maybe I'm reading the specs wrong.

If you confirm a proper chip, please link me to it as it will be much appreciated.

The LD29300V50 has a 5 volt output.

We have the NCP5667 here: LDO 5 volt, 3.0 amp regulator, D2Pak3 , nice reg but no control.

LD29300P2M50R, Obsolete
LD29300V50, nice, no control
LK112M50TR, only 100ma output but nice size

I was going by Mouser's product page, which shows the LD29300P2M33R is 5V 5A with a control pin. According to the spec sheet, it appears Mouser is wrong. However, the Diodes AP1184 is available in a TO263 package which is only a hair wider than the D2PAK. I double checked the spec sheet, everything is kosher.

Apparantly Mouser can't be trusted for anything. Their page shows it as a 3A reg.
