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 300 mA. The LP3982 is available in an 8-pin MSOP package that is pin-and-package compatible with Maxim's MAX8860. Also available in the LM3982 in a small size 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). Low dropout voltage allows more utilization of the available energy of the battery near the end of its life voltage. The PMOS output transistor of the LP3982 consumes relatively no drive current, compared to PNP LDO regulators.
This PMOS regulator is small ceramic capacitor (2.2μF typical) load stable.
These devices also include regulated fault detection, bandgap reference voltage, constant current limit, and thermal overload protection.
