LD39030DTPU105R Description

Short technical summary and product information.

The STMicroelectronics LD39030DTPU105R is a linear voltage regulator designed for power management applications. It provides a fixed output voltage of 1.05V and can supply a continuous output current of up to 300mA. The device accepts an input voltage range up to 5.5V.

 

Key electrical characteristics include a low quiescent current of 40 µA and a maximum voltage dropout of 0.33V at 300mA. The regulator also offers a PSRR ranging from 80dB to 55dB across the 1kHz to 100kHz frequency range. Protection features include over current, over temperature, and soft start.

 

This component is housed in a compact 4-DFN (1x1) package, specifically a 4-XDFN exposed pad, suitable for surface mount applications. It operates within a wide temperature range of -40°C to 125°C (TJ).

 

The LD39030DTPU105R is RoHS3 compliant and has an MSL rating of 1 Unlimited.
