LP3982 Datasheet | National Semiconductor

Description The LP3982 low-dropout (LDO) CMOS linear regulator is available in 1.8V, 2.5V, 2.77V, 2.82V, 3.0V, 3.3V, and adjustable versions. They deliver 300m A of output current. Packaged in an 8-Pin MSOP, the LP3982 is pin and package patible with Maxim’s MAX8860. The LM3982 is also available in the small footprint LLP package. The LP3982 suits battery powered applications because of its shutdown mode (1n A typ), low quiescent current (90µA typ), and LDO voltage (120m V typ). The low dropout voltage allows for more utilization of a battery’s available energy by operating closer to its end-of-life voltage. The LP3982’s PMOS output transistor consumes relatively no drive current pared to PNP LDO regulators. This PMOS regulator is stable with small ceramic capacitive loads (2.2µF typ). These devices also include regulation fault detection, a bandgap voltage reference, constant current limiting and thermal overload protection.
