LD3985M27R Description

Short technical summary and product information.

The STMicroelectronics LD3985M27R is a low-dropout linear voltage regulator designed for various applications requiring a stable 2.7V output. It can supply up to 150mA of current and features a low voltage dropout of 0.1V at 150mA. The device operates within a temperature range of -40°C to 125°C.

 

Key electrical characteristics include a maximum input voltage of 6V and protection features such as over current and over temperature shutdown. The PSRR is rated between 60dB and 50dB across the 1kHz to 10kHz frequency range. The regulator has an 'Enable' control feature.

 

This component is supplied in a SOT-23-5 package, suitable for surface mounting. Its compact size and reliable performance make it a good choice for power management in space-constrained electronic devices. The RoHS status is listed as RoHS3 Compliant, and it has a Moisture Sensitivity Level (MSL) of 1.
