Part Number : LT1085, LT1085CT-5
Function : 3A, Low Dropout Positive Fixed Regulator
Package : TO-220 and DD Type
Manufactures : Linear Technology
The LT1085 series of positive adjustable regulators are designed to provide 7.5A, 5A and 3A 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 specified as a function of load current. Dropout is guaranteed at a maximum of 1.5V at maximum output current, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress on both the regulator and power source circuitry under overload conditions. The LT1083 / LT1084 / LT1085 devices are pin compatible with older 3-terminal regulators. A 10μF output capacitor is required on these new devices. However, this is included in most regulator designs.
