2 / 24 page www.ti.com ABSOLUTE MAXIMUM RATINGS DISSIPATION RATINGS RECOMMENDED OPERATING CONDITIONS ELECTRICAL CHARACTERISTICS TPS60250 SLVS769 – APRIL 2007 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. over operating free-air temperature range (unless otherwise noted)(1) VALUE UNIT VI Input voltage range (all pins) –0.3 to 7 V MAX Output current limit 650 mA HBM ESD Rating (2) 2 kV CDM ESD Rating(3) 500 V MM ESD Rating(4) 200 V TA Operating temperature range –40 to 85 °C TJ Maximum operating junction temperature 150 °C TST Storage temperature –55 to 150 °C (1) 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 under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The Human body model (HBM) is a 100-pF capacitor discharged through a 1.5-k Ω resistor into each pin. The testing is done according JEDECs EIA/JESD22-A114. (3) Charged Device Model (4) Machine Model (MM) is a 200-pF capacitor discharged through a 500-nH inductor with no series resistor into each pin. The testing is done according JEDECs EIA/JESD22-A115.
