Part Number: LP3982
Function: Ultra Low-Dropout, Low-Noise, 300 mA, CMOS Regulator
Package: SOP 8 Pin
Manufacturer: Texas Instruments
Pinouts:
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 adjustable versions. They deliver 300mA of output current. Packaged in an 8-Pin VSSOP, the LP3982 is pin and package compatible with Maxim’s MAX8860. The regulator is also available in the small footprint WSON package.
The LP3982 suits battery-powered applications because of its shutdown mode (1nA typ), low quiescent current (90 μA 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 (2.2 μF typ). These devices also include regulation fault detection, a bandgap voltage reference, constant current limiting and thermal overload protection.
