3 / 23 page ![]() LP38798 www.ti.com SNOSCT6A – MARCH 2013 – REVISED MAY 2013 ABSOLUTE MAXIMUM RATINGS (1) IN –0.3V to 22V OUT –0.3V to VIN +0.3V FB, EN –0.3V to 6.0V Storage Temperature Range –65°C to +150°C Soldering(2) 260°C, 10 sec ESD Rating (HBM)(3) 2 kV Power Dissipation(4) Internally Limited IOUT (Survival) Internally Limited (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. Operating Range conditions indicate the conditions at which the device is functional and the device should not be operated beyond such conditions. (2) Peak Reflow Temperatures for Surface Mount devices are defined in “Absolute Maximum Ratings for Soldering,” Literature Number: SNOA549C (3) The Human Body Model (HBM) is a 100 pF capacitor discharged through a 1.5 k Ω; resistor into each pin. Applicable test standard is JESD-22-A114-C. (4) The value of θJ−A for the WSON package is dependent on PCB copper area, copper thickness, the number of copper layers in the PCB, and the number of thermal vias under the exposed thermal pad (DAP). Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator may go into thermal shutdown. See 12-Lead WSON Package Thermal Considerations in the Applications Information. OPERATING RATINGS (1) Input Voltage, VIN 3.0V to 20.0V Output Voltage, VOUT 1.2V to (VIN – VDO) Enable Voltage, VEN 0.0V to 5.0V Junction Temperature, TJ –40°C to +125°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. Operating Range conditions indicate the conditions at which the device is functional and the device should not be operated beyond such conditions.
