3A Low Dropout Positive Regulators
TM

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.
In addition, on-chip trimming adjusts the
reference voltage tolerance to 1% maximum
at room temperature and 2% maximum over
the 0 to 125°C range for the LX8385A. The
LX8385B offers 0.8% tolerance at room
temperature and 1.0% maximum over line,
load and temperature. Fixed versions are
also available and specified in the Available
Options table below.
The LX8385/85A/85B Series devices are
pin-compatible
with
regulators, such as the 117 series products,
but they do require input and output
capacitors. A minimum 10μF capacitor is
required on the input and a 15μF or greater
on the output of these new devices for
stability. Although, these capacitors are
generally included in most regulator designs.
The LX8385/85A/85B Series quiescent
current flows into the load, thereby
increasing efficiency. This feature contrasts
with PNP regulators where up to 10% of the
output current is wasted as quiescent
current.
The LX8385-xxI is specified over the
industrial temperature range of -25°C to
125°C, while the LX8385-xxC / 85A-xxC /
85B-xxC is specified over the commercial
range of 0°C to 125°C.
