一,
产品概述(General Description) 
JTMB8503 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 400mV（</span>Vin =4.0V、</span>Vout=3.0V）。</span>The
very low power consumption of JTMB8503 （</span>Iq=3.0uA）</span>can greatly improve natural life
of batteries.
JTMB8503 can provide output value in the range of 1.2V~6.0V in 0.1V steps. It also can
customized on command.
JTMB8503 includes high accuracy voltage reference, error amplifier, current limit circuit
and output driver module.
JTMB8503 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%.
JTMB8503 is available in SOT-89-3、</span>SOT-23-3,TO-92 packages which is lead free，</span>it
also can available in these packages with lead.
