EMP8733 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP LDO in SOT-23 Package General Description The EMP8733 Features ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 300m A output current and supports preset output voltages ranging from 0.8V to 4.5V with 0.05V increment. Based on its low quiescent current consumption, the EMP8733 is ideal for battery-powered applications. The high power supply rejection ratio of the EMP8733 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads (1µF typical). The EMP8733 is Available in miniature 3-pin SOT-23-3 package.
