The R1191L045B-TR is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output current of 300mA. It operates within an input voltage range of 3.5V to 16.0V and offers an output voltage range from 2.0V to 15.0V in 0.1V increments. The device features a low supply current of approximately 50µA in fast mode and only 0.3µA in standby mode, making it suitable for low-power applications. This regulator includes reverse current protection, which prevents current from flowing back into the VDD pin when the output voltage exceeds the input voltage, enhancing its reliability in backup circuits. It also incorporates thermal shutdown and short-circuit protection features. The typical dropout voltage is 0.55V at 300mA output, and it provides a ripple rejection of 60dB at 1kHz. The R1191L045B-TR is available in compact packages such as DFN1616-6, SOT-23-5, and SOT-89-5, allowing for high-density mounting on circuit boards. It is recommended for use in power sources for digital home appliances and audio-visual equipment.
