Can some one give information about the below part marking

18 TI 233

I was assuming that it is a LDO, if you have any part number associated with above part marking please share it.

Regards

Vijay.

Hello Vijay,

Please send a picture of the device. Using the Part Marking Lookup Tool: Packaging Part Marking Lookup | Texas Instruments (ti.com) it may be one of two devices.

Thank you,

Hi Leonard,

we will try get to the image as the part was very small we couldn't capture image of it very clearly, meanwhile Is it possible for you tell us about in which category this part might fall under? LDO or switching regulator or any other power related category?

Regards

Vijay

Here are the two devices with 18 marking. One is an 8-pin device, the other a 4-pin device:

Part number	Marking	Package \| Pins

BQ298018RUGR	18	RUG \| 8

BQ298018RUGR

RUG | 8

TLV74018PDQNR	18	DQN \| 4

TLV74018PDQNR

DQN | 4

The TLV74018 is an LDO.

Hope this helps,

~Leonard

Hello Vijay,

Please confirm there are 8 pads on the package/pcb conforming to this package drawing: https://www.ti.com/lit/ml/mpqf215a/mpqf215a.pdf .

Looking at the EVM, the pads are obvious, but I cannot tell from your picture if they are the same on your device.
