STMicroelectronics Fixed 5V LDO Voltage Regulator, 1.5A Output, TO-252-3

The STMicroelectronics LD29150DT50R is a low drop-out (LDO) voltage regulator engineered for precision and reliability. It provides a fixed 5V output voltage with an impressively low dropout of just 400mV (typical at 1.5A), making it exceptionally efficient in systems where maintaining a stable voltage with minimal headroom is critical. Its very low ground current further enhances efficiency, particularly beneficial for battery-powered or energy-sensitive applications.

This regulator is designed to handle high current loads up to a guaranteed 1.5A, yet its superb characteristics also make it ideal for lower-current systems where the tiny dropout voltage is a primary requirement. The device ensures a highly accurate output, with a tolerance of ±1% at 25°C. For robust protection, it includes internal current and thermal limiting, safeguarding both the regulator and your circuit from damage under fault conditions.

With a wide input voltage range of 6V to 30V, this positive polarity, single-output regulator offers great versatility for various power management designs. Its surface-mount TO-252-3 (DPAK) package is industry-standard, facilitating easy integration into automated assembly processes. The component is built to operate reliably across an extensive temperature range from -40°C to 125°C, ensuring stable performance in demanding environments.

Whether you are developing consumer electronics, industrial control systems, or automotive modules, this LDO regulator provides a compact, high-performance solution for stabilising your power supply with minimal voltage loss.
