STMicroelectronics LK112
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.| Part No. | LK112 |

DESCRIPTION
SOT23-5LFEATURES
● 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 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
