LP3982IMM-3.3

TEXAS INSTRUMENTS  LP3982IMM-3.3  固定电压稳压器, LDO, 2.5V至6V, 120mV压差, 3.3V输出, 300mA输出, VSSOP-8

The is a 3.3V fixed output low-dropout LDO CMOS Linear Regulator deliver 300mA of output current. The device suits battery-powered applications because of its shutdown mode, low quiescent current and LDO voltage. The low-dropout LDO voltage allows for more utilization of a battery"s available energy by operating closer to its end-of-life voltage. The LP3982 device"s PMOS output transistor consumes relatively no drive current compared to PNP LDO regulators. This PMOS regulator is stable with small ceramic capacitive loads 2.2µF typical. These devices also include regulation fault detection, a bandgap voltage reference, constant current limiting and thermal-overload protection.
