The Semtech Corporation SC561ULTRT is a dual-output linear voltage regulator IC designed for efficient power management. This component features two fixed positive outputs, 2.85V and 3.1V, each capable of supplying up to 300mA. With a low quiescent current of 60 µA and a maximum supply current of 85 µA, it is suitable for battery-powered applications. The SC561ULTRT offers important control features including Enable and Power Good signals, along with robust protection mechanisms such as Over Temperature, Short Circuit, and Under Voltage Lockout (UVLO). Its high Power Supply Rejection Ratio (PSRR) of 65dB at 1kHz ensures clean power delivery. The ultralow profile 8-MLPQ-UT (1.5x1.5) package, supplied in Tape & Reel (TR), facilitates compact designs. This device finds application in portable electronics, wireless communication systems, and various industrial control systems where reliable voltage regulation is critical. It operates within a temperature range of -40°C to 85°C and supports an input voltage up to 5.5V, with a typical dropout voltage of 0.25V at 250mA.
