EMP8042-High Input Voltage,Low Quiescent Current,Low-Dropout Linear RegulatorDataSheet

General Description
    The EMP8042 is a high voltage, low quiescent current, low dropout regulator with 100mA output driving capacity. The EMP8042, which operates over an input range of 3V to 20V, is stable with any capacitors, whose capacitance is larger than 1μF, and suitable for powering battery-management ICs because of the virtue of its low quiescent current consumption and low dropout voltage. Below the maximum power dissipation (please refer to Note. 5), It guarantees delivery of 100mA output current, and supports preset output voltages ranging from 1.3V to
6.0V with 0.1V increment.
    EMP8042 also includes bandgap voltage reference, constant current limiting and thermal overload protection. It’s available in miniature SOT-89-3 packages.
