LD57100J105R Description

Short technical summary and product information.

The STMicroelectronics LD57100J105R is a linear voltage regulator designed for power management applications. It offers a stable 1.05V fixed output voltage and can supply up to 1A of current. The device operates within a temperature range of -40°C to 85°C (TJ).

 

Key electrical characteristics include a low voltage dropout of 0.08V at 1A and a PSRR of 75dB at 1kHz. Protection features such as over current and over temperature are integrated for enhanced reliability. The regulator also includes an enable control feature.

 

This component is housed in a compact 6-FlipChip (0.78x1.18) package, specifically a 6-XFBGA, FCBGA, and is designed for surface mounting. Its specifications make it suitable for various electronic designs requiring a reliable linear voltage regulation.

 

Compliance information indicates RoHS3 compliance, MSL 1 Unlimited, and REACH Unaffected status, though these are based on available database information and may require verification.
