The LTC3544BEUD#TRPBF is a high-efficiency, high-voltage, low-dropout (LDO) linear voltage regulator from Analog Devices. It operates with an input voltage range of 2.7V to 5.5V, and provides a 5.0V output. It is capable of supplying up to 500mA of output current with a dropout voltage of 260mV at 500mA. The LTC3544BEUD#TRPBF accepts bypass and shutdown input control pins, allowing for improved noise and power consumption. It also features an adjustable current limit, and under voltage lockout protection. It is available in a small, space-saving, SOIC-8 package, making it an ideal choice for applications where space is at a premium.
