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
