LD39300PT18-R Description

Short technical summary and product information.

The LD39300PT18-R from STMicroelectronics is a high-performance, ultra-low dropout BiCMOS linear voltage regulator. It is designed to operate from a 2.5V to 6V input supply and delivers a stable 1.8V output voltage with a guaranteed 3A output current. The device boasts a very low quiescent current, making it suitable for low-voltage microprocessor and memory applications.

 

Key electrical characteristics include an ultra-low dropout voltage of 40mV typically at 600mA load and 200mV typically at 3A load. The output voltage tolerance is ±1.5% at 25°C. Protection features include over-current and over-temperature limits, along with logic-controlled electronic shutdown.

 

This regulator is available in a PPAK package, suitable for surface mounting. It operates across a wide temperature range of -40°C to 125°C. The device is stable with ceramic capacitors, simplifying external component selection for various applications like microprocessor power supplies and DSP power supplies.
