LN1231

LN1231 300mA Low Dropout CMOS Voltage Regulator ■ General Description The LN1231 series are highly precise, low power consumption, positive voltage regulators manufactured using CMOS and laser trimming technologies. The series provides large currents with a significantly small dropout voltage. The LN1231 consists of a current limiter circuit, a driver transistor, a precision reference voltage and an error amplifier. Output voltage is selectable in 0.1V steps between 1.3V ~ 6.0V. SOT-23 and SOT-89 packages are available. ■ Applications  Power supply for DVD and CD-ROM drives  Power supply for battery-powered devices  Power supply for personal communication devices  Power supply for note PCs ■ Ordering Information LN1231 P ③④⑤⑥ ①② ■ Features  Output voltage: 1.2V to 6.0V（selectable in 100mV steps）  High-accuracy output voltage: ± 2.0%  Low dropout voltage: 160mV @100mA (3.0 type)  Low current consumption: 4.0 µA (typ.)  Maximum Outp...
