... The output is preset at 3.3V for the MAX882/MAX884 and 5V for the MAX883. In addition, all devices employ Dual Mode™ operation, allowing user-adjustable outputs from 1.25V to 11V using external resistors. The input volt- age supply range is 2.7V to 11.5V. ...

... Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS ( (MAX883 4.3V (MAX882/MAX884 unless otherwise noted.

... The MAX882/MAX883/MAX884 are micropower, low- dropout linear regulators designed primarily for battery- powered applications. They feature Dual Mode operation, allowing a fixed output of 5V for the MAX883 and 3.3V for the MAX882/MAX884 adjustable output from 1.25V to 11V. These devices supply up to 200mA while requiring less than 15µ ...

... Input Bypass Capacitor Normally, use 0.1µF to 10µF capacitors on the MAX882/ MAX883/MAX884 input. The best value depends pri- marily on the power-up slew rate of V and line transients. Larger input capacitor values pro- vide better supply-noise rejection and line-transient response, as well as improved performance, when the supply has a high AC impedance ...

... This application is limited to short-term battery backup for 3.3V circuits. The current drawn by the MAX882’s OUT pin at 3.3V during reverse-current protection is typically 8µA. It should not be used with the MAX883 and MAX884, since the OFF pin is a logic input, and indeterminate inputs can cause the regulator to turn on intermittently, draining the battery ...
