Unlike normal NPN transistor design, where the base to emitter voltage drop and collector to emitter saturation voltage.

The TS39100/1/2/3/4/5 are 1A ultra low dropout linear voltage regulators that provide low voltage, high current output from an extremely small package. These regulators offers extremely low dropout (typically 400mV at 1A) and very low ground current .
