ABLIC Inc. Voltage Regulators - Linear S-1137B24-M5T1U

The S-1137B24-M5T1U is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output voltage ranging from 1.2 V to 3.5 V, selectable in 0.05 V increments. It operates with an input voltage between 1.7 V and 5.5 V and offers an output current capability of up to 300 mA, provided the input voltage exceeds the output voltage by at least 1.0 V. The device features a typical dropout voltage of 210 mV at 2.8 V output and a low current consumption of 45 OºA during operation, which increases to a maximum of 65 OºA. In power-off mode, the current consumption is significantly reduced to 0.1 OºA. The regulator includes built-in protection features such as overcurrent protection and a soft-start circuit with a typical soft-start time of 0.7 ms. It also supports the use of a ceramic capacitor of 1.0 OºF or more for input and output, ensuring compatibility with various capacitor types. The device is suitable for applications in battery-powered devices, cellular phones, and portable electronics, and operates within a temperature range of -40°C to +85°C. The S-1137B24-M5T1U is available in compact SOT-89-5, SOT-23-5, and SNT-6A(H) packages, facilitating high-density mounting in electronic designs.
