Description
The LK112 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 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 LK112 has a very low quiescent current in on mode while in off mode Iq is reduced below 100 nA max. The internal thermal shutdown circuitry limits the junction temperature below 150 °C. Load current is internally monitored and the device shuts down in the presence of a short-circuit or overcurrent condition on the output.
Features
? Output current up to 150 mA
? Low-dropout voltage (350 mV at IOUT = 150 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
