Description

V REG LDO 0.3A 1.8V 3982 MSOP8
The LP3982 low-dropout (LDO) CMOS linear regulator is available in 1.8-V, 2.5-V, 2.82-V, 3-V, 3.3-V, and adjustable versions. They deliver 300 mA of output current. Packaged in an 8-pin VSSOP, the LP3982 is pin- and package-compatible with Maxim's MAX8860. The LM3982 is also available in the small footprint WSON package. The LP3982 suits battery-powered applications because of its shutdown mode (1 nA typical), low quiescent current (90 μA typical), and LDO voltage (120 mV typical). 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 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 (2.2 μF typical). These devices also include regulation fault detection, a bandgap voltage reference, constant current limiting, and thermal-overload protection.
