STMicroelectronics LDK130M28RY Low-Dropout Regulator

The LDK130M28RY from STMicroelectronics is a high-performance low-dropout (LDO) voltage regulator designed to deliver a stable and precise output voltage. This LDO is ideal for noise-sensitive applications where a clean power supply is necessary. The device ensures a maximum dropout voltage of just 200 mV at full load, which is particularly beneficial for systems with a low input-to-output voltage differential.

With a fixed output voltage of 2.8V, the LDK130M28RY can supply up to 300 mA of output current, making it suitable for powering microcontrollers, sensors, and other low-power electronic devices. The regulator's high accuracy, with a typical output voltage tolerance of ±1%, ensures reliable operation of the connected components.

One of the key features of the LDK130M28RY is its low quiescent current, which is typically 50 µA in idle mode and decreases to less than 1 µA in shutdown mode. This characteristic makes the LDO an excellent choice for battery-powered applications, where power efficiency is crucial to extend battery life.

The device also includes several safety features to protect the electronic system. These include thermal shutdown, which prevents damage from overheating, and current limiting, which safeguards the regulator and the load from excessive current draw. Additionally, the LDK130M28RY is designed to be stable with low ESR ceramic capacitors, ensuring reliable performance and simplifying the design process.

The LDK130M28RY comes in a compact SOT-89 package, which is suitable for space-constrained applications. The small footprint of the regulator allows for its integration into a wide range of electronic devices without compromising on performance.

Overall, the LDK130M28RY LDO voltage regulator from STMicroelectronics offers a blend of high performance, reliability, and energy efficiency, making it an excellent choice for designers looking to optimize their power management solutions.
