LD39020DTPU31R Description

Short technical summary and product information.

The LD39020DTPU31R from STMicroelectronics is a linear voltage regulator designed for efficient power management. It provides a stable, fixed output voltage of 3.1V and can deliver up to 200mA of current. The device operates with an input voltage range up to 5.5V, making it suitable for various battery-powered and portable applications.

 

Key electrical characteristics include a low voltage dropout of 0.35V at 200mA and a quiescent current of 40µA, contributing to power efficiency. The regulator also features a Power Supply Rejection Ratio (PSRR) ranging from 80dB to 55dB across a frequency range of 1kHz to 100kHz, helping to filter out noise from the power supply.

 

Designed for surface mounting, the LD39020DTPU31R is supplied in a 4-XDFN exposed pad package, measuring 1x1mm. This compact form factor is ideal for space-constrained designs. The operating temperature range is -40°C to 125°C (TJ), ensuring reliable performance in demanding environments. Protection features include over-current, over-temperature, and soft-start capabilities.
