General Description MAX1615EUK+T

The MAX1615/MAX1616 are micropower, SOT23-5 linear regulators that supply 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  MAX1615/MAX1616 have excellent line-transient  response and AC power-supply rejection ratio. They  provide a clean, fixed 5V or 3.3V output (MAX1615) or  an adjustable 1.24V to 28V output (MAX1616), even  when subjected to fast supply-voltage changes that  occur during the switchover from battery to AC adapter  input power. The space-saving SOT23-5 package has  excellent thermal characteristics and tolerates up to  571mW of power dissipation. Fault protection is provided  by internal foldback current limiting and thermalshutdown  circuitry. The MAX1615/MAX1616 are now  available in lead-free packages.
