LP3982IMM-ADJ/NOPB

Стабилизатор с малым падением напряжения, регулируемый, 2.5В до 6В (Vin), 120мВ, 1.25В до 6В/0.3А.

The LP3982IMM-ADJ/NOPB is a micro-power ultra-low-dropout low-noise CMOS Linear Regulator delivers 300mA of output current. The LP3982 suits battery-powered applications because of its shutdown mode (1nA typical), low quiescent current (90µA typical) and LDO voltage (120mV typical). The low dropout voltage allows for more utilization of a battery available energy by operating closer to its end-of-life voltage. The LP3982 device PMOS output transistor consumes relatively no drive current compared to PNP LDO regulators. This device also includes regulation fault detection, a band-gap voltage reference, constant current limiting and thermal-overload protection. This PMOS regulator is stable with small ceramic capacitive loads (2.2µF typical). The regulator topology is the classic type with negative feedback from the output to one of the inputs of the error amplifier.
