(2) Typical Values represent the most likely parametric norm. (3) IFULLLOAD is defined in the current limit curves. The IFULLLOAD Curve defines the current limit as a function of input-to-output voltage. Note that 30W power dissipation for the LM1084 is only achievable over a limited range of input-to-output voltage. (4) Load and line regulation are measured at constant junction temperature, and are ensured up to the maximum power dissipation of 30W. 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: LM1084 |
