LD49100PU33RY Description

Short technical summary and product information.

The STMicroelectronics LD49100PU33RY is a linear voltage regulator designed for power management applications. It offers a stable 3.3V fixed output voltage and can deliver a maximum output current of 1A. The device operates with a maximum input voltage of 5.5V and exhibits a low voltage dropout of 0.4V at 1A.

 

Key electrical characteristics include a quiescent current of 50 µA and a supply current of up to 300 µA. The PSRR is rated between 65dB and 62dB across the 1kHz to 10kHz frequency range. Protection features include over-current and over-temperature protection, enhancing system reliability.

 

This regulator is housed in a compact 6-VDFN exposed pad package, suitable for surface mount assembly with wettable flanks. It operates across a wide temperature range from -40°C to 125°C (TJ), making it suitable for demanding environments. The series is noted as Automotive, AEC-Q100 compliant.
