illustrate
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 offer an output current of 300mA. In an 8-pin MSOP package, the pin and package LP3982 are compatible with Maxim's MAX8860. The LM3982 is also available in a small LLP package.
The LP3982 is suitable for battery-powered applications due to its shutdown mode (1NA typical), low quiescent current (90μA typical), and LDO voltage (120mV typical). The low dropout voltage allows for more of the battery's usable energy utilization, operating voltages close to the end of its life. The output drive current consumption of the PMOS transistor of the LP3982 is relatively less than that of the PNP LDO regulator.
The PMOS regulator is stable with small ceramic (2.2μF typical) capacitive loads.
These devices also include regulated fault detection, bandgap reference voltage, constant current limiting, and thermal overload protection.
