Features

Fixed 1.25V or Adjustable (1.25V to 6.5V) Output
Low Cost
Thermal Overload Protection
Output Current Limit
Reverse Battery Protection
Low 0.1nA Off Supply Current
Low 80µA Full-Load Supply Current

Additional Details

The MAX1749 allows for a constant vibration force while operating from a +2.5V to +6.5V input range and delivering up to 120mA. A PMOS pass transistor allows the 80µA supply current to remail independent of the load.

The output voltage can be adjusted from +1.25V to V_IN with an external resistor-divider. When turned off (ON = low), the MAX1749 supply current drops to 1µA (max) to minimize battery drain. Other features include short-circuit protection, thermal shutdown protection, and reverse battery protection. The MAX1749 is available in a 5-pin SOT23 package.
