LC1218
250mA Low Consumption Linear Regulator
DESCRIPTION
LC1218 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 420mV ( Vout= 3.3V), And it also provides foldback short‐ circuit protection and output current limit function. The very low power consumption of LC1218(Iq=2.0uA)can greatly improve natural life of batteries.

EXPLANATION
LC1218 is a series of low dropout voltage and low power consumption three pins regulator. Its application circuit is very simple, which only needs two outside capacitors. It is composed of these modules: high accuracy voltage reference, current limit circuit, error amplifier, output driver and power transistor. Current Limit module can keep chip and power system away from danger when load current is more than 250mA. LC1218 uses trimming technique to assure the accuracy of output value within±2%, at the same time, temperature compensation is elaborately considered in this chip, which makes LC1218’s temperature coefficient within 100ppm/℃。
LC1218 has well load transient response and good temperature characteristic, And it uses trimming technique to guarantee output voltage accuracy within±2%.
