The 400mOhm typical Rds(on) at 5V input means a voltage drop of about 40mV at 100mA load.
The TPS2049DR integrates fixed current limiting, over-temperature protection, and UVLO.
No LTB risk or obsolescence pressure exists for this device.
Yes, the TPS2049DR supports a load voltage range of 2.7V to 5.5V, which covers 3.3V and 5V rails used in USB and general power distribution.
