LK112Sxx
Low noise low drop voltage regulator with shutdown function
Features

Output current up to 200 mA Low dropout voltage (500 mV max at IOUT = 200 mA) Very low quiescent current: 0.1 uA in OFF mode and max 250 uA in ON mode at IOUT = 0 mA Low output noise: typ 30 uV 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) capacitor can be used connected to the noise bypass pin to lower the output noise level to 30 uVrms. An internal PNP pass transistor is used to achieve a low dropout voltage. The LK112Sxx has a very low quiescent current in ON MODE while in OFF MODE the Iq is reduced down to 100 nA max. The internal thermal shutdown circuitry limits the junction temperature to below 150 C. The load current is internally monitored and the device will shutdown in the presence of a short circuit or overcurrent condition at the output.
SOT23-5L

Description
The LK112Sxx is a low dropout linear regulator with a built in electronic switch. The internal switch can be controlled by TTL or CMOS logic levels. The device is ON state when the control pin is pulled to a logic high level. An external Table 1. Device summary
