LR9103
Preliminary
LOW NOISE 150mA LDO
REGULATOR
CMOS IC
 DESCRIPTION
The UTC LR9103 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 LR9103, 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 LR9103 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 LR9103.
The UTC LR9103 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.
