Linear Technologies component identification

Need help identifying surface mount component 10 pin MSOP package. Markings on front: “LTCNS” above linear logo and “e3” below. Markings on back are: “19” (suspect date) “Malay” (origin?) and 4158. It is in a power supply section and pin 3 is connected through a resistor to a power MOSFET.

Thanks for any help.

Welcome to the Tech Forum.

I am looking into this for you.

Hi ctemps160,

It’s the LT4356xMS-1, with “x” calling out the temperature. The “e3” refers to matte tin lead-free terminals. Currently, we only have the commercial temp versions (0°C to 70°C) and military temp versions (–55°C to 125°C) in stock.
