LP3982
Micropower, Ultra Low-Dropout, Low-Noise, 300mA
CMOS Regulator
General Description
The LP3982 low-dropout (LDO) CMOS linear regulator is
available in 1.8V, 2.5V, 2.77V, 2.82V, 3.0V, 3.3V, and adjust-
able versions. They deliver 300mA of output current. Pack-
aged 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.
