CS1112YDWFR24

Power Distribution Switches, Load Drivers Overview

The CS1112YDWFR24 is a dual-channel, low-dropout (LDO) linear voltage regulator manufactured by onsemi. It provides fixed output voltages of 2.4V per channel with high line and load regulation capabilities. The device operates with an input voltage range up to 5.5V and delivers a maximum output current of 300mA per channel. Key electrical specifications include a typical dropout voltage of 200mV at full load and a quiescent current of 60µA. It features built-in thermal shutdown and overcurrent protection for robust operation in space-constrained applications.
