LMS1585 National Semiconductor, LMS1585 Datasheet - Page 5

• Manufacturer Part Number: LMS1585
• Description: 5A and 3A Low Dropout Fast Response Regulators
• Manufacturer: National Semiconductor

Typicals and limits appearing in normal type apply for T
tion temperature range for operation, 0˚C to 125˚C for commercial grade and −40˚C to 125˚C for industrial grade.
Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: The maximum power dissipation is a function of T
is P
Note 3: For testing purposes, ESD was applied using human body model, 1.5k
Note 4: Typical Values represent the most likely parametric norm.
Note 5: All limits are guaranteed by testing or statistical analysis.
Note 6: Load and line regulation are measured at constant junction temperature, and are guaranteed up to the maximum power dissipation of 30W. Power dissipa-
tion is determined by the input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
Note 7: The minimum output current required to maintain regulation.
Note 8: I
Note 9: Consult factory for other fixed voltage options.
