LDQ40PU25RY ST LDO Regulator | 6-DFN(2x2) | 4.0V, 250mA, Low Dropout

Product Overview

The LDQ40PU25RY from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for space-constrained applications. Housed in a compact 6-DFN (2x2 mm) package, it delivers a fixed output voltage of 2.5V with a maximum output current of 250mA. The device features a low dropout voltage of typically 200mV at full load, making it ideal for battery-powered and portable electronics. With an input voltage range from 2.5V to 5.5V, it is compatible with standard 3.3V and 5V supply rails. The LDQ40PU25RY integrates protection features such as thermal shutdown and current limiting, ensuring reliable operation in demanding environments.
