no, the device is temporarily re-assembled.

it's just a 3pin sot-23 package with power going in, ground and power coming out.
i just dont know the voltage or the current limit.

just the code in bold - no room for any logo on a sot23

i may be able to get another later and just meter it - it's in a high-end flashlight between the battery and mcu.

Here are some without the logo
Looks like some of the markings are:
1.5V = 65E9
1.8V = 65K5
3.0V = 65Z5
3.3V = 662K
This datasheet for the XC6202 series has a voltage chart that might help
