Operating Ratings are conditions for which the device is intended to be functional, but device parameter specifications may not be ensured. For specifications and test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) Under normal operation the VC and CE pins may go to voltages above this value. The maximum rating is for the possibility of a voltage being applied to the pin, however the VC and CE pins should never have a voltage directly applied to them. (4) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. See the Electrical Characteristics table for the thermal resistance of various layouts. The maximum allowable power dissipation at any ambient temperature is calculated using: PD (MAX) = (TJ(MAX) − TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. (5) The human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin per JEDEC standard JESD22-A114. Operating Conditions Operating Junction Temperature Range (1) −40°C to +125°C Storage Temperature −65°C to +150°C Supply Voltage 2.5V to 7V Maximum SW Voltage 20V VGH Voltage Range 5V to 30V Op-Amp Supply, AVIN 4V to 14V (1) All limits specified at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are 100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). Copyright © 2005–2013, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LM3310 |
