The LX8818 features on-chip trimming of the internal voltage enabling precise output voltages, typically 1% of it's specified value, while the BiPolar output transistor has a low dropout voltage even at full output current (VDO < 1.2V typ. @ 1A). Output voltage overshoot is minimized when VIN is applied, typically VOUT overshoot < 2% for VIN 1V/uS ramp.
