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)

TDFN

Junction-to-Ambient Thermal Resistance (θJA)...........41°C/W

Junction-to-Case Thermal Resistance (θJC)..................9°C/W

Side-Wettable TDFN

Junction-to-Ambient Thermal Resistance (θJA)...........41°C/W

Junction-to-Case Thermal Resistance (θJC)..................8°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

(Circuit of Figure 1; VIN = 1.8V, VOUT = 1.2V, EN = IN for MAX15029, EN = BIAS for MAX15030, IOUT = 100mA, TA = TJ = -40°C to

+125°C. Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)
