Outline
LR8503 series is a group of positive
voltage output, low power consumption, low
dropout voltage, three terminal regulator. It
can provide 250mA output current when
input / output voltage differential drops to
400mVVin =4.0V Vout=3.0V The
very low power consumption of LR8503
Iq=3.0uA can greatly improve natural life
of batteries.
LR8503 can provide output value in the
range of 1.2V~6.0V in 0.1V steps. It also can
customized on command.
LR8503 includes high accuracy voltage
reference, error amplifier, current limit circuit
and output driver module.
LR8503 has well load transient response
and good temperature characteristic, which
can assure the stability of chip and power
system. And it uses trimming technique to
guarantee output voltage accuracy within
2%.
LR8503 is available in SOT-89-3SOT-
23-3 packages which is lead freeit also
can available in these packages with lead.

Application hints
NOTE1 Input capacitor (Cin=1uF) is recommended in
all application circuit. Tantalum capacitor is
recommended.
NOTE2Output capacitor (Cout=1uF) is recommended
in all application to assure the stability of
circuit. Tantalum capacitor is recommended.
