LT1086CT-3.3#PBF Product Details

The LT1086CT-3.3#PBF 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 reference/ouput voltage to 1%. Current limit is also trimmed, minimizing the stress on both the regulator and powersource circuitry under overload conditions.

The LT1086CT-3.3#PBF is pin compatible with older 3-terminal adjustableregulators. A minimum 10µF output capacitor isrequired on these devices.

The LT1086CT-3.3#PBF offers excellent line and load regulation specifications and ripple rejection exceeds 75dB even at the maximum load current of 1.5A. The LT1086CT-3.3#PBF 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 LT1086CT-3.3#PBF is available in a 3-pin TO-220 package and a space-saving surface mountable 3-pin DD package.
