Description
The OEC7040B is a dual channel low dropout linear regulator that belongs to the IC Chips product category. It operates from 2.5V to 5.5V input voltage and can deliver up to 300mA output current per channel. The typical dropout voltage is only 270mV at 300mA. This component is an excellent choice for battery-powered appliances as it has low quiescent current, high PSRR, and low noise. It also features a logic-controlled shutdown mode, over-temperature protection, short-circuit current-limit, and current-limit protection to ensure proper output current. The OEC7040B is available in SOT-23-6, TSOT-23-6A, and TDFN1.6x1.6-6 packages.
