www.ti.com 7 Specifications 7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VIN –0.3 6 Input voltage V EN –0.3 VIN + 0.3 Operating –55 150 Temperature Junction, Tj 150 °C Storage, Tstg –65 170 (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
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.
7.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VIN Supply input voltage range (IL = 0 mA, TA = 25°C) VREF + 0.02(1) 5.5 V (1) See Figure 7-28 in Section 7.6 for minimum input voltage at different load currents and temperature
