LDLN025PU50R Description

Short technical summary and product information.

The STMicroelectronics LDLN025PU50R is a linear low-dropout (LDO) voltage regulator designed for efficient power management. It provides a stable 5V output voltage with a maximum output current of 250mA.

 

Key electrical characteristics include an ultra-low quiescent current of 250µA, an input voltage range of 1.5V to 5.5V, and a typical dropout voltage of 120mV at 250mA. The regulator features excellent PSRR performance and includes protection features such as over current, over temperature, short circuit, and soft start.

 

This device is suitable for applications requiring clean power delivery and minimal noise. Its fixed output type and enable control feature simplify circuit design. The operating temperature range is from -40°C to 125°C.

 

The LDLN025PU50R is packaged in a small 4-DFN (1x1) surface-mount package, making it ideal for space-constrained designs. The mounting type is Surface Mount.
