PRODUCTION DATA SHEET

Three-Terminal Adjustable Or

Fixed Output

The LX8385/85A/85B Series ICs are

The LX8385/85A/85B Series devices are

positive regulators designed to provide 3A pin-compatible with earlier 3-terminal

output current. These regulators yield regulators, such as the 117 series products,

higher efficiency than currently available but they do require input and output

devices with all internal circuitry designed capacitors. A minimum 10µF capacitor is

to operate down to a 1V input-to-output required on the input and a 15µF or greater

differential. In each of these products, the on the output of these new devices for

dropout voltage is fully specified as a stability. Although, these capacitors are

function of load current. Dropout is generally included in most regulator designs.
