Description:

3A Fast Ultra Low Dropout Linear Regulators

Features

* n n n n n n n n n n n n Ultra low dropout voltage Low ground pin current Load regulation of 0.08% 1µA quiescent current in shutdown mode Guaranteed output current of 3A DC Available in TO-263 and TO-220 packages Output voltage accuracy ± 1.5% Error flag indicates output status Sense option improves

Applications

* The LP3873/LP3876 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3873/LP3876 to operate under extremely low dropout conditions. Dropout Voltage: Ultra low dropout voltage; typically 80mV at 300mA l
