Troubleshooting handsoldered TPS73633 SOT-23 LDO whose output is unexpectedly high
That LDO regulator requires a minimum output current to regulate properly. In the data sheeet it states that the output regulates with loads between 1 mA and 400 mA. It is likely that with no load resistor the output rises up above the stated regulated output voltage.

Elsewhere in the data sheet it "implies" 20 mA is the minimum (table 1, page 16). It's almost always a good idea to use an input capacitor so don't scrimp on this either (see 8.3.3.1). Output capacitors are usually needed to improve load transient responses and this is particularly an issue on digital circuits so please use one.

If all of this does not restor proper operation then re-check the pin-outs to make sure you have not wired it up incorrectly.
