DescriptionThe 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 300mA of output current. Packaged in an 8-Pin MSOP, the LP3982 is pin and package compatible 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 (1nA typ), low quiescent current (90µA typ), and LDO voltage (120mV 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 compared 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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
