High-Voltage, Low-Power Linear Regulators
for Notebook Computers
________________General Description
The MAX1615/MAX1616 are micropower, SOT23-5 lin-
ear 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 qui-
escent 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 provid-
ed by internal foldback current limiting and thermal-
shutdown circuitry. The MAX1615/MAX1616 are now
available in lead-free packages.
