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. (2) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, RθJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using the equation for P(MAX): P(MAX) = (TJ(MAX) – TA) / RθJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. See Power Supply Recommendations for additional information on heatsinking and thermal resistance. (3) When used in dual-supply systems where the regulator load is returned to a negative supply, the output voltage must be diode-clamped to ground. (4) May exceed the input supply voltage. 6.2 ESD Ratings VALUE UNIT Electrostatic Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V(ESD) V discharge (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT Operating junction temperature −40 125 °C Input supply voltage 2.3 30 V 4 Submit Documentation Feedback Copyright © 2004–2015, Texas Instruments Incorporated Product Folder Links: LP2952-N LP2952A LP2953 LP2953A |
