The LT
®
1086 is designed to provide up to 1.5A output
current. All internal circuitry is designed to operate down
to 1V input-to-output differential and the dropout voltage
is fully specified as a function of load current. Dropout is
guaranteed at several operating points up to a maximum
of 1.5V at maximum output current. Dropout decreases at
lower load currents. On-chip trimming adjusts the refer-
ence/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 minimum 10µF output capacitor is
required on these devices.
The LT1086 offers excellent line and load regulation speci-
fications and ripple rejection exceeds 75dB even at the
maximum load current of 1.5A. The LT1086 is floating
architecture with a composite NPN output stage. All of the
quiescent current and the drive current for the output
stage flows to the load increasing efficiency.
The LT1086 is available in a 3-pin TO-220 package and a
space-saving surface mountable 3-pin DD package.
