3A LOW DROPOUT POSITIVE REGULATORS

DESCRIPTION
The LX8385/8385A/8385B series ICs are
positive regulators designed to provide
3A output current. Each regulator yields
higher efficiency than currently available
devices with all internal circuitry designed
to operate down to a 1V input-to-output-
differential. In these products, the drop-
out voltage is fully specified as a function
of load current. The LX8385's dropout is
guaranteed at a maximum of 1.5V at maxi-
mum output current, decreasing at lower
load currents. The LX8385A/85B have a
maximum dropout voltage of 1.3V.
The LX8385B offers a tighter voltage
reference tolerance: ±1.0% over line, load
and temperature, with 0.8% initial accu-
racy. The LX8385/85A have 1.0% initial
accuracy, with 2% over line, load and tem-
perature.
The LX8385/85A/85B series devices are
pin-compatible with earlier 3-terminal
regulators, such as 117 series products.
While a 10µF output capacitor is required
on both input and output of these new
devices, this is generally included in most
regulator designs.
The quiescent current of the LX8385/
85A/85B series products flows into the
load, increasing efficiency. This feature
contrasts with PNP regulator designs,
where up to 10% of the output current is
wasted as quiescent current.
The LX8385-xxI is rated for -25°C to
+125°C applications, and the LX8385-xxC
/8385B-xxC is rated for 0°C to +125°C
applications.
