产品概述

描述

The LK112S is a low-dropout linear regulator with shutdown function. The internal switch can be controlled by TTL or CMOS logic levels. The device is ON when the control pin is pulled to a high logic level. An external capacitor can be connected to the noise bypass pin to reduce the output noise level to 30 μVrms. An internal PNP pass transistor is used to achieve a low-dropout voltage. The LK112S has a very low quiescent current in ON mode while in OFF mode the Iqis reduced to 100 nA max. The internal thermal shutdown circuitry limits the junction temperature below 150 °C. The load current is internally monitored and in the presence of a short-circuit or overcurrent conditions at the output, the device shuts down.
  • 所有功能

    • 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)
