Texas Instruments LP3982ILD-ADJ/NOPB
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-pinVSSOP, the LP3982 is pin- and package-compatible with Maxims MAX8860. The LM3982 is also availablein the small footprint WSON package.
The LP3982 suits battery-powered applications because of its shutdown mode (1 nAtypical), low quiescent current (90 µA typical), and LDO voltage (120 mV typical). The low dropoutvoltage allows for more utilization of a battery’s available energy by operating closer to itsend-of-life voltage. The LP3982 devices PMOS output transistor consumes relatively no drivecurrent compared to PNP LDO regulators.
This PMOS regulator is stable with small ceramic capacitive loads (2.2 µFtypical).
These devices also include regulation fault detection, a bandgap voltage reference,constant current limiting, and thermal-overload protection.
