ing current-limit protection, short-circuit protection, over-pVO嘉泰姆

temperature protection, and UVLO. The current-limit andpVO嘉泰姆

short-circuit protection can protect down-stream devicespVO嘉泰姆

from catastrophic failure by limiting the output current atpVO嘉泰姆

current-limit threshold during over-load or short-circuitpVO嘉泰姆

events. When VOUT drops below VIN-1.5V the devices limitpVO嘉泰姆

the current to a lower and safe level. The over-tempera-pVO嘉泰姆
