LDLN025PU30R Description

Short technical summary and product information.

The STMicroelectronics LDLN025PU30R is a linear low-dropout (LDO) voltage regulator designed for applications requiring low noise and stable power delivery. It provides a fixed output voltage of 3V and can supply up to 250mA of current.

 

Key electrical specifications include an input voltage range of 1.5V to 5.5V, a typical quiescent current of 250µA, and a dropout voltage of 250mV at 250mA. The regulator also features high PSRR performance across a wide frequency range (80dB to 60dB from 100Hz to 100KHz) and includes protection features such as over-current, over-temperature, short-circuit, and soft-start.

 

The LDLN025PU30R is available in a 4-DFN (1x1) surface-mount package, making it suitable for space-constrained designs. Its operating temperature range is -40°C to +125°C.

 

This LDO is well-suited for various power management applications where low noise and efficiency are critical, such as portable electronics, battery-powered devices, and noise-sensitive analog circuits.
