LD39150DT25-R Description

Short technical summary and product information.

The STMicroelectronics LD39150DT25-R is a linear voltage regulator designed for efficient power management. It provides a stable, fixed output voltage of 2.5V and can deliver up to 1.5A of current. The device operates across a wide temperature range from -40°C to 125°C.

 

This regulator is housed in a DPAK (TO-252-3, DPak (2 Leads + Tab), SC-63) surface mount package, making it suitable for space-constrained applications. Key electrical characteristics include a low voltage dropout of 0.4V at 1.5A and protection features against over current and over temperature conditions. Its PSRR performance ranges from 65dB to 55dB across a frequency band of 120Hz to 1kHz.

 

The LD39150DT25-R is a single-regulator device, ideal for applications requiring a reliable and compact power solution. Its design considerations include efficient thermal management due to its surface mount package and operating temperature range.
