Looking for a 3.3V LDO regulator with different pinout

hello,
I am looking for a SOT-23-5 or SOT-25 3.3V LDO regulator.
The original one has been blown and there are no marks except for a 3V3.
Every similar LDO I have searched has no identical pinout.
The majority have Pin 1 as Input and Pin 5 as Output. Those two pins are connected at the PCB so such a pinout is not acceptable.
Looking for an LDO with a pinout like this:
Pins 1-5 ---> Vin - Enable (Shorted)
Pin 2 -----> Ground
Pin 3 -----> Capacitor to ground
Pin 4 -----> Vout
Right now I dont want to make any modification to use another LDO.
So i am looking for the right one.

TAR5S33 seems exactly the same!
RT9193-33 more mA but wrong pinout...
NJM2888F is also good!
Thanks all!

Oops, sorry, my copy & paste failed, the RT chip was from a previous search... I actually meant NJM2888F.
