Principio de funcionamiento<\/h2>\n

PMOS pass element achieves low dropout. Error amplifier and trimmed bandgap reference maintain 3.3V output with \u00b12% accuracy. 40 \u00b5A quiescent current is independent of load, ideal for always-on battery systems. Current limit and thermal shutdown provide fault protection. EN pin enables\/disables the output.<\/p>\n
