Description
The MAX1658/MAX1659 linear regulators maximize battery life by combining ultra-low supply currents and low dropout voltages. They feature Dual Mode™ operation, which presets the output to 3.3V (MAX1658) or 5V (MAX1659), or permits it to be adjusted between 1.25V and 16V. The regulator supplies up to 350mA, with a typical dropout of 650mV for the MAX1658 and 490mV for the MAX1659. With their P-channel MOSFET pass transistor, these devices maintain a low quiescent current from zero output current to the full 350mA, even in dropout. They support input voltages ranging from 2.7V to 16.5V.

The MAX1658/MAX1659 feature a 1µA shutdown mode, reverse battery protection, short-circuit protection, and thermal shutdown. They are available in a special high-power (1.2W), 8-pin SO package designed specifically for compact applications.
