Product Description
STMicroelectronics LDLN025M12R is a high-performance voltage regulator designed for low-noise, low-power applications. Featuring a compact SOT-23 5-pin surface mount package, this regulator operates within an input voltage range from 1.5 V to 5.5 V and delivers output current up to 250 mA.
Its ultra low output noise of 6.5 μVRMS and very low quiescent current of 12 μA at no load make it ideal for circuits requiring high signal fidelity and energy efficiency. The device maintains a very low dropout voltage of 250 mV at 250 mA load, optimizing performance in battery-powered and portable systems.
The LDLN025M12R provides an output voltage accuracy of ±2% across variations in line, load, and temperature, ensuring stable voltage supply. It incorporates logic-controlled electronic shutdown and output discharge features for enhanced control and system safety. Additionally, internal soft-start reduces inrush current, enhancing reliability.
This regulator includes comprehensive overcurrent and thermal protection mechanisms, capable of sustaining operation over an extended temperature range from -40 °C to +125 °C, suitable for industrial and automotive environments.
Its SOT-23 surface mount package (dimensions 2.95 mm length × 1.65 mm width × 1.3 mm height) supports compact, efficient PCB designs. The device's applications include power management in telecommunications, instrumentation, automotive electronics, and consumer electronics where precise, stable voltage regulation is critical.
