LK112
Low noise and low drop voltage regulator with shutdown function
Datasheet - production data
• Internal current and thermal limit
• 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)
Description
SOT23-5L
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
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.
