L465 – STMicroelectronics

The STMicroelectronics L465 is a monolithic voltage regulator providing a fixed 5V output at a current of up to 1.5A. This linear regulator utilizes internal current limiting and thermal shutdown protection to enhance device robustness. The L465, as indicated by the “STM/85+” marking, is likely fabricated using an older process technology predating RoHS compliance. Engineers should carefully inspect incoming units for bent or misaligned pins prior to board mounting, as this is a known potential defect. The device requires external input and output capacitors for stable operation, with recommended values detailed in the manufacturer’s datasheet. Due to its non-RoHS status, the L465 should not be specified for new designs requiring compliance with Restriction of Hazardous Substances directives.
