The LX8610 family are positive
very low dropout regulators
. They are
designed to provide a power supply for
very low headroom applications, such as
3.3V– 2.5V.
BiCMOS technology
allows an
effective series pass element resistance,
R
DS(ON)
of 250m
dropout voltage of 250mV at 1A.
Low Quiescent Current and Logic-
Controlled Shutdown
help conserve
battery
life
and
efficiency. Typical quiescent current is
under 400μA irrespective of load
increase
system
current, while the shutdown current is
only 10μA. The device will enter
shutdown mode when the ENABLE pin
is pulled low.
Thermal & Short-Circuit Current
Limiting:
the LX8610 limits the current
when the output is shorted, so protecting
sensitive load circuits. The device will
also turn off if the junction temperature
exceeds 155°C.
Available in small outline SOT-223
and 8-pin SOIC:
Adjustable versions
use the 8-pin SOIC and fixed output
voltage devices are supplied in the 3-lead
SOT-223.
IMPORTANT:
