Product Summary
The LP3874EMPX-ADJ/NOPB is a fast ultra low-dropout linear regulator. It operates from a +2.5V to +7.0V input supply. The ultra low dropout linear regulator responds very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3874EMPX-ADJ/NOPB is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3874EMPX-ADJ/NOPB to operate under extremely low dropout conditions. The applications of the LP3874EMPX-ADJ/NOPB include Microprocessor power supplies, GTL, GTL+, BTL, and SSTL bus terminators, Power supplies for DSPs, SCSI terminator, Post regulators, High efficiency linear regulators, Battery chargers and Other battery powered applications.
