The LT
1086 is designed to provide 1.5A with higher
efficiency than currently available devices. All internal
circuitry is designed to operate down to 1V input-to-
output differential and the dropout voltage is fully speci-
fied as a function of load current. Dropout is guaranteed at
a maximum of 1.5V at maximum output current, decreas-
ing at lower load currents. On-chip trimming adjusts the
reference/ouput voltage to 1%. Current limit is also
trimmed, minimizing the stress on both the regulator and
power source circuitry under overload conditions.
The LT1086 is pin compatible with older 3-terminal adjust-
able regulators. A 10
μ
F output capacitor is required on
these new devices; however, this is usually included in
most regulator designs.
A 2.85V output version is offered for SCSI-2 active termi-
nation. For surface mount applications see the LT1117-
2.85 data sheet. For high current or lower dropout require-
ments see the LT1123-2.85 data sheet.
Unlike PNP regulators, where up to 10% of the output
current is wasted as quiescent current, the LT1086 quies-
cent current flows into the load, increasing efficiency.
