LD49100PU18RY Description

Short technical summary and product information.

The STMicroelectronics LD49100PU18RY is a high-performance linear voltage regulator designed to provide a stable 1.8V output at up to 1A of current. With a maximum input voltage of 5.5V and a low voltage dropout of 0.4V at 1A, this device is suitable for various power management applications.

 

Key electrical characteristics include a PSRR of 65dB to 62dB across the 1kHz to 10kHz frequency range and a quiescent current of 50 µA. Protection features such as over-current and over-temperature are integrated for enhanced reliability.

 

The regulator operates within a temperature range of -40°C to 125°C (TJ). It is supplied in a 6-DFN (3x3) package and features a Surface Mount, Wettable Flank mounting type, making it ideal for compact electronic designs.

 

Compliance includes RoHS3, MSL 1 Unlimited, and REACH Unaffected statuses, though these are noted as having low confidence due to unverified data.
