The STMicroelectronics LD39300DT25-R is an ultra-low dropout BiCMOS linear voltage regulator designed for applications requiring stable power delivery. It provides a guaranteed 3A output current with a typical dropout voltage of 200mV at 3A load. The device operates from a 2.5V to 6V input supply and offers a fixed 2.5V output voltage with a tolerance of ±1.5% at 25°C.
Key features include logic-controlled electronic shutdown, internal current and thermal limiting, and fast dynamic response to line and load changes. Its low quiescent current, typically 1.2mA at 3A load, makes it suitable for low voltage microprocessor and memory applications. The regulator is stable with ceramic capacitors, simplifying external component selection.
This component is supplied in a DPAK (TO-252-3) surface mount package, facilitating integration into compact electronic designs. The operating temperature range is -40°C to 125°C, ensuring reliable performance in various environmental conditions. Typical applications include microprocessor power supplies, DSP power supplies, and post-regulators for switching supplies.
