LP3982IMM-2.77 Description
The LP3982 low-dropout (LDO) CMOS linear regulator isavailable 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 packagecompatible with Maxim’s MAX8860. The LM3982 is alsoavailable in the small footprint LLP package.The LP3982 suits battery powered applications because ofits shutdown mode (1nA typ), low quiescent current (90μAtyp), and LDO voltage (120mV typ). The low dropout voltageallows for more utilization of a battery’s available energy byoperating closer to its end-of-life voltage. The LP3982’sPMOS output transistor consumes relatively no drive currentcompared to PNP LDO regulators.
