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 capacitor can be used connected to the noise bypass pin to lower the output noise level to 30 µVrms. 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.
Features
■ 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
