1.5A Low Dropout Positive Regulators
PRODUCTION DATA SHEET
DESCRIPTION
The LX8386/86A/86B Series ICs are The LX8386/86A/86B series devices are
positive regulators designed to provide 1.5A pin-compatible with earlier 3-terminal
output current. These regulators yield regulators, such as the 117 series products.
higher efficiency than currently available While a 10µF output capacitor is required on
devices with all internal circuitry designed both input and output of these new devices,
to operate down to a 1V input-to-output this capacitor is generally included in most
differential. In each of these products, the regulator designs.
dropout voltage is fully specified as a The LX8386/86A/86B series quiescent
