The LK112Sxx is a low noise low drop voltage regulator with shutdown function. Its features include: output current up to 200 mA; low dropout voltage (500 mV max at IOUT = 200 mA); very low quiescent current: 0.1 µA in OFF mode and max 250 µA in ON mode at IOUT = 0 mA; low output noise: typ. 30 µV at IOUT = 60 mA and 10 Hz < f < 80 kHz; wide range of output voltages; internal current and thermal limit; VOUT tolerance ± 2% (at 25 °C); operative input voltage from VOUT + 0.5 to 14 V (for VOUT > 2 V) or from 2.5 V to 14 V (for VOUT < 2 V).
