MAX1615, MAX1616 High-Voltage, Low-Power Linear Regulators For Notebook Computers

The MAX1615 MAX1616 are micropower, SOT23-5 linear Regulators that supply always-on, keep-alive power to CMOS RAM and Microcontrollers (Cs) in systems with High-Voltage batteries. Key features include wide input voltage range, low dropout voltage, and low quiescent supply current.
Despite a miserly 8A (max) no-load supply current, the MAX1615 MAX1616 have excellent 4f4 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 thermal-shutdown circuitry. The MAX1615 MAX1616 are now available in lead-free packages.
