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 provide an output current of 300mA. In an 8-pin MSOP package, the LP3982 is pin-and-package compatible with Maxim's MAX8860. The LM3982 is also available in a small size LLP package.
The LP3982 is suitable for battery-powered applications because of its shutdown mode (1NA typical), low quiescent current (90μA typical), and LDO voltage (120mV typical). Low dropout voltage allows more of the battery's available energy utilization, operating close to its end-of-life voltage. The output drive current of the LP3982's PMOS transistor is relatively unchanged compared to that of a PNP LDO regulator.
This PMOS regulator is capacitively loaded with small ceramic (2.2μF typical).
These devices also include regulated fault detection, bandgap reference voltage, constant current limit, and thermal overload protection.
