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.
PACKAGE THERMAL CHARACTERISTICS (Note 1)
SC70
Junction-to-Ambient Thermal Resistance ( θ JA ) .........324°C/W
Junction-to-Case Thermal Resistance ( θ JC ) ..............115°C/W
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial .
ELECTRICAL CHARACTERISTICS
(V IN = V OUT + 0.5V, T A = -40°C to +85°C, unless otherwise noted. C IN = 1μF, C OUT = 1μF. Typical values are at T A = +25°C; the
MAX8892 is tested with 2.45V output, unless otherwise noted.) (Note 2)
