Microsemi Corp. Special Purpose Regulators LX8384-00CDD

The LX8384-00CDD is a low dropout positive voltage regulator capable of delivering up to 5A output current. It features a guaranteed maximum dropout voltage of 1.3V at full load, ensuring efficient operation even with a low input-to-output voltage differential. The device is designed with on-chip trimming that provides a reference voltage tolerance of 2.0% maximum over a temperature range of 0¬8C to 125¬8C, making it suitable for applications requiring precise voltage regulation. This regulator is compatible with various applications, including powering Intel Pentium P54C processors, battery chargers, and constant current regulators. It requires external input and output capacitors for stability, with a minimum of 10¬µF on the input and 15¬µF on the output. The LX8384-00CDD is available in a 3-pin plastic TO-263 package and is specified for operation within a temperature range of -25¬8C to 125¬8C. Engineers considering this product should note its efficiency advantages over traditional PNP regulators, as it minimizes quiescent current loss.
