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 ¬8C, ensuring reliable performance in various environments.
