DESCRIPTION
The UTC
LR9102/A
is a typical LDO (linear regulator) with the
features of high output voltage accuracy, low supply current, low
ON-resistance, and high ripple rejection.
During operation of the UTC
LR9102/A,
the dropout voltage is
very low and the response of line transient and load transient are
very well.
Internally, there’re many functions of UTC
LR9102/A
which can
be seen in the block figure. There are a voltage reference unit, an
error amplifier, resistor-net for voltage setting, a current limit circuit,
and a chip enable circuit in each UTC
LR9102/A,
with auto
discharge function at off state.
The UTC
LR9102/A
can be used as an ideal of the power supply
for hand-held communication equipment, such as: power source for
portable communication equipment, power source for electrical
appliances, for example, cameras, VCRs and camcorders and
power source for battery-powered equipment.
