STMicroelectronics Voltage Regulators - Linear LK112SM28TR

The LK112SM28TR is a low-dropout linear voltage regulator designed to provide a stable output voltage with a maximum output current of 200 mA. It features a low dropout voltage of 500 mV at full load, making it suitable for applications where space and efficiency are critical. The device operates with a very low quiescent current of 0.1 µA in OFF mode and up to 250 µA in ON mode when no load is present. This regulator offers low output noise, typically 30 µV at an output current of 60 mA, which is beneficial for sensitive electronic applications. The input voltage range is flexible, allowing operation from VOUT + 0.5 V to 14 V for output voltages greater than 2 V, or from 2.5 V to 14 V for output voltages less than 2 V. The LK112SM28TR includes internal current and thermal limiting features to protect against overcurrent and overheating conditions. The output voltage tolerance is ± 2% at 25 °C, ensuring reliable performance in various environments.
