LD39020ADTPU18R Description

Short technical summary and product information.

The STMicroelectronics LD39020ADTPU18R is a low-dropout linear voltage regulator designed for efficient power management. It provides a stable 1.8V output voltage with a maximum output current of 200mA.

 

Key electrical characteristics include a low quiescent current of 40µA and a PSRR ranging from 80dB to 55dB across the 1kHz to 100kHz frequency range. The device features protection against over current, over temperature, and includes a soft start function. Its dropout voltage is rated at 0.35V at 200mA.

 

This regulator is suitable for surface mount applications, utilizing a compact 4-DFN (1x1) or 4-XDFN exposed pad package. The operating temperature range is -40°C to 125°C (TJ), making it versatile for various environmental conditions.

 

It is designed with an 'Enable' control feature for power management flexibility. The RoHS status is indicated as RoHS3 Compliant, and the Moisture Sensitivity Level (MSL) is 1 Unlimited.
