LD39300PT-R Description

Short technical summary and product information.

The STMicroelectronics LD39300PT-R is a fast, ultra-low dropout linear voltage regulator designed for low voltage microprocessor and memory applications. It operates from a 2.5V to 6V input supply and offers a guaranteed 3A output current.

 

Key features include an ultra-low dropout voltage (200mV typ. @ 3A), very low quiescent current (1.2mA typ. @ 3A load), and logic-controlled electronic shutdown. The device has internal current and thermal limit protection. It is available in a PPAK package for surface mounting.

 

This regulator is suitable for applications such as microprocessor power supplies, DSPs power supplies, and post regulators for switching supplies. It is stable with ceramic capacitors and offers fast dynamic response to line and load changes. The output voltage is adjustable from 1.22V up to 5V, with a typical output voltage tolerance of ±1.5% at 25°C.
