The LT1086CT is a low dropout Positive Regulator 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 decreases at lower load currents. On-chip trimming adjusts the reference/output voltage to 1%. Current limit is also trimmed, minimizing the stress on both the regulator and power source circuitry under overload conditions. It is pin compatible with older 3-terminal adjustable regulators. A minimum 10uF output capacitor is required on these devices. The LT1086 offers excellent line and load regulation specifications 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 flow to the load increasing efficiency.
