2 / 31 page ABSOLUTE MAXIMUM RATINGS DISSIPATION RATING TABLE TPS2552 TPS2553, TPS2552-1, TPS2553-1 SLVS841C – NOVEMBER 2008 – REVISED SEPTEMBER 2009...................................................................................................................................... www.ti.com This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C, Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated voltages to these high-impedance circuits. During storage or handling the device leads should be shorted together or the device should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriate logic voltage level, preferably either VCC or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.

(2) Maximum ambient temperature is a function of device junction temperature and system level considerations, such as load current, power dissipation and board layout. See dissipation rating table and recommended operating conditions for specific information related to these devices. (3) Add an R suffix to the device type for tape and reel. over operating free-air temperature range unless otherwise noted (1) (2) VALUE UNIT Voltage range on IN, OUT, EN or EN, ILIM, FAULT –0.3 to 7 V Voltage range from IN to OUT –7 to 7 V IO Continuous output current Internally Limited See the Dissipation Rating Continuous total power dissipation Table Continuous FAULT sink current 25 mA ILIM source current 1 mA HBM 2 kV ESD CDM 500 V TJ Maximum junction temperature –40 to 150 °C Tstg Storage temperature –65 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) Voltages are referenced to GND unless otherwise noted.
