BL8553
400mA CMOS Low Dropout Voltage Low consumption Regulator
Features：
：
Outline：
：
BL8553 series is a group of positive
voltage output, low power consumption, low
dropout voltage, three terminal regulator. It
can provide 200mA output current when
input / output voltage differential drops to
470mV（Vout=2.0V）。The very low power
consumption of BL8553（Iq=7uA）can
greatly improve natural life of batteries.
