DESCRIPTION

The LX8385/85A/85B Series ICs are positive regulators designed to provide 3A output current. These regulators yield higher efficiency than currently available devices with all internal circuitry designed to operate down to a 1V input-to-output differential. In each of these products, the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.3V (8385A/B) and 1.5V (8385) at maximum output current, decreasing at lower load currents.
