MAX8863T/S/R, Low-Dropout, 120mA Linear Regulators MAX8864T/S/R
Absolute Maximum Ratings
VIN to GND ...-7V to +7V Operating Temperature Range ... -40°C to +85°C Output Short-Circuit Duration ... Infinite Operating Temperature SET to GND ..-0.3V to +7V Range (MAX8863TMUK/PR3+).. -55°C to +125°C SHDN to GND ..-7V to +7V Junction Temperature ..+150°C SHDN to IN ..-7V to +0.3V Storage Temperature Range .. -65°C to +150°C OUT to GND ...-0.3V to (VIN + 0.3V) Lead Temperature (soldering, 10s) ...+300°C Continuous Power Dissipation (multilayer board, TA = +70°C) Soldering Temperature (reflow) ...+260°C SOT23 (3.9mW/°C above +70°C) ..312.6mW 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)
SOT23 Junction-to-Ambient Thermal Resistance (θJA) ...255.9°C/W Junction-to-Case Thermal Resistance (θJC) ...81°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
