The bandgap reference provides \u00b12% output accuracy. The 25uA quiescent current is achieved through optimized bias circuitry while maintaining regulation and noise performance. The enable pin allows external power sequencing, and the 1uA shutdown current minimizes battery drain when disabled. Thermal shutdown and overcurrent protection safeguard against fault conditions.","pin_description":"
