STMicroelectronics LK112M17TR Low Dropout Regulator

The LK112M17TR from STMicroelectronics is a high-performance, low dropout linear voltage regulator designed to deliver a continuous output current of up to 200 mA. This component is part of the LK112 series, which is well-suited for battery-powered applications due to its low quiescent current and low dropout voltage, ensuring efficient power management and extended battery life.

With a fixed output voltage of 1.7V, the LK112M17TR provides a stable and precise voltage supply for microcontrollers, sensors, and other sensitive electronic circuits. The device features an impressive low dropout voltage, typically only 100 mV at 100 mA load, allowing it to maintain a regulated output even when the supply voltage is very close to the output voltage.

One of the key features of the LK112M17TR is its thermal shutdown and short-circuit protection, which safeguard the device and the application from damage due to overheating or fault conditions. Additionally, the regulator offers a low quiescent current of just 50 µA in the off mode, which is particularly beneficial for portable and battery-powered applications where power conservation is crucial.

The LK112M17TR is available in a compact SOT-23-5 package, making it an excellent choice for space-constrained applications. Its small footprint and surface-mount form factor facilitate easy integration into a wide range of electronic systems. The device also supports a wide operating temperature range from -40°C to +125°C, allowing for reliable performance across various environmental conditions.

Designed with an eye on reliability and efficiency, the STMicroelectronics LK112M17TR low dropout regulator is an ideal choice for designers looking to optimize power consumption without sacrificing performance in their next-generation electronic products.
