www.ti.com 7 Specifications 7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
IN –0.3 13 V Input voltage EN –0.3 IN + 0.3 V Output voltage VOUT –0.3 5.5 V Output short circuit current ISC 20 mA Operating temperature range TA –55 150 °C Storage temperature range Tstg –65 170 °C (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. These are stress ratings only and functional operation of the device at these or any other conditions beyond those specified in the Electrical Characteristics Table is not implied.
7.2 ESD Ratings VALUE UNIT
Human-body model (HBM), per ANSI/ESDA/ JEDEC JS-001(1) ±2500 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1500 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
