ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VIN = +5.0V, capacitor values from Table 2, TA = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)

ELECTRICAL CHARACTERISTICS

(VIN = +5.0V, capacitor values from Table 2, TA = -40°C to +85°C, unless otherwise noted.) (Note 3)

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.

Note 2: Once started, the MAX1682/MAX1683 typically operate down to 1V.

Note 3: Specifications at -40°C to +85°C are guaranteed by design.

Note 1: Avoid shorting OUT to GND, as it may damage the device. For temperatures above +85°C, shorting OUT to GND even

instantaneously will damage the device.
