EMP8738-High Accuracy 30mA CMOS LDO


EMP8738-High Accuracy 30mA CMOS LDO In SOT-23 Package DataSheet

General Description
    The EMP8738 features low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 30mA 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 EMP8738 is ideal for battery-powered applications. The high power supply rejection ratio of the EMP8738 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads (1μF typical). The EMP8738 is available in miniature 3-pin SOT-23-3 package.
    EMP products are Halogen free and RoHS compliant.
