The MAX1616EUK+T is a high-voltage, low power linear regulator for notebook computers in 5 pin SOT-23 package. It is a linear regulator that supplies always-on, keep-alive power to CMOS RAM and microcontrollers (μCs) in systems with high-voltage batteries. Key features include wide input voltage range, low dropout voltage and low quiescent supply current. Despite a miserly 8μA (max) no-load supply current, the MAX1616 have excellent line-transient response and AC power-supply rejection ratio. It provide a clean an adjustable 1.24V to 28V output, even when subjected to fast supply-voltage changes that occur during the switchover from battery to AC adapter input power. It is an excellent thermal characteristic and tolerates up to 571mW of power dissipation. Fault protection is provided by internal foldback current limiting and thermal shutdown circuitry.
