PT4403-低压差350mA电流调整器

GENERAL DEION

The PT4403 is a low dropout current regulator with 350mA constant current sink. The dropout voltage is typically 110mV and the quiescent current is only 100uA. Without any external components required, the PT4403 occupies very small space and provides a low cost solution. The PT4403 can be used as a high current LED driver, as well as a current sink. The built-in thermal shutdown protection shuts down the chip when the chip temperature exceeds 150oC. PT4403 is packaged in SOT-89 and SOT-252
