♦ 4V to 28V Input Range

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.

♦ 8µA (max) Quiescent Supply Current

♦ <1µA Shutdown Supply Current

♦ 3.3V or 5V, Pin-Selectable Output (MAX1615)

Adjustable 1.24V to 28V Output (MAX1616)

Despite a miserly 8µA (max) no-load supply current, the

MAX1615/MAX1616 ha ve e xc e lle nt line -tra ns ie nt

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.

♦ 30mA Output Current

♦ ±2% Initial Output Accuracy

♦ Thermal-Overload Protection

♦ 5-Pin SOT23 Package

♦ Low Cost
