STMicroelectronics Voltage Regulator 5.5V Low Dropout 300mA Surface Mount SOT-23 5-Pin LDK130M18RY

STMicroelectronics LDK130M18RY is a compact 5.5 V low dropout voltage regulator designed for efficient power management in electronic circuits. Housed in a surface mount SOT-23 5-pin package with dimensions 2.95 mm length, 1.6 mm width, and 1.3 mm height, this device delivers a stable 300 mA output current with a typical dropout voltage of just 100 mV. It operates from a wide input voltage range of 1.9 V to 5.5 V, making it suitable for a variety of low-power and battery-driven applications.

The regulator's low quiescent current of 120 µA and a logic-controlled electronic shutdown mode enable extremely low current consumption, less than 1 µA, during disablement, extending battery life. The output voltage tolerance is ± 2.0% at 25 °C, ensuring high accuracy and stability in regulated outputs. Compatibility with ceramic capacitors for output stabilization enhances overall performance and noise reduction.

For protection and application robustness, the LDK130M18RY integrates internal current and thermal limit features, safeguarding against overload and overheating conditions. Its extended temperature range from -40 °C to 125 °C further supports use in automotive and industrial environments, aligning with AEC-Q100 automotive qualification to meet rigorous reliability standards.
