ELECTRICAL CHARACTERISTICS (TJ = 25°C unless otherwise stated) V mV % mV % V DESCRIPTION The LM1086 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 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 output voltage to 1%. Current limit is also trimmed, minimising the stress on both the regulator and power source circuitry under overload conditions. The LM1086 is pin compatible with older 3 terminal adjustable regulators. A 10 m F output capacitor is required on these new devices; however, this is usually included in most regulator designs. Unlike PNP regulators, where up to 10% of the output current is wasted as quiescent current, the LM1086 quiescent current flows into the load, increasing efficiency. |
