Regulators
General Description
Features
The LMS1585AEP and LMS1587EP are low dropout positive
regulators with output load current of 5A and 3A respectively.
Their low dropout voltage (1.2V) and fast transient response
make them an excellent solution for low voltage microproces-
sor applications.

Note 4: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 5: The maximum power dissipation is a function of TJ(max) , θJA, and TA. The maximum allowable power dissipation at any ambient temperature
is PD = (TJ(max)–T A)/θJA. All numbers apply for packages soldered directly into a PC board.
Note 6: For testing purposes, ESD was applied using human body model, 1.5kΩ in series with 100pF.
Note 7: Typical Values represent the most likely parametric norm.
Note 8: All limits are guaranteed by testing or statistical analysis.
Note 9: Load and line regulation are measured at constant junction temperature, and are guaranteed up to the maximum power dissipation of 30W. Power
dissipation 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 10: The minimum output current required to maintain regulation.
Note 11: IFULLLOAD is 5A for LMS1585AEP and 3A for LMS1587EP.
Note 12: Consult factory for other fixed voltage options.

Application Note
Output Voltage
The adjustable version develops at 1.25V reference voltage,
(VREF), between the output and the adjust terminal. As shown
in Figure 1, this voltage is applied across resistor R1 to gen-
erate a constant current I1. This constant current then flows
through R2. The resulting voltage drop across R2 adds to the
reference voltage to sets the desired output voltage.
The current IADJ from the adjustment terminal introduces an
output error. But since it is small (120μA max), it becomes
negligible when R1 is in the 100Ω range.
For fixed voltage devices, R1 and R2 are integrated inside the
devices.
