4 / 22 page  LM1085 SNVS038G – JULY 1999 – REVISED MARCH 2013 www.ti.com Electrical Characteristics (continued) Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the operating junction temperature (TJ) range of -40°C to +125°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only.

Power dissipation is determined by the input/output differential and the output current. Ensured maximum power dissipation will not be available over the full input/output range. (5) Dropout voltage is specified over the full output current range of the device. (6) The minimum output current required to maintain regulation. 4 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LM1085 |
