EMP8040

ESMT/EMP EMP8040 High Input Voltage, Low Quiescent Current, Low-Dropout Linear Regulator General Description The EMP8040 is a high voltage, low quiescent current, low dropout regulator with 100mA output driving capacity. The EMP8040, which operates over an input range of 3V to 36V, 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. EMP8040 also includes bandgap voltage reference, constant current limiting and thermal overload protection.
