LOW NOISE LOW DROP VOLTAGE REGULATOR WITH SHUTDOWN FUNCTION
1/11January 2003 OUTPUT CURRENT UP TO 150mA LOW DROPOUT VOLTAGE (350mV AT OUT =150mA) VERY LOW QUIESCENT CURRENT: 0.1μA
IN OFF MODE AND MAX 250μA IN ON
MODE AT I OUT =0mA LOW OUTPUT NOISE: TYP 30μV AT OUT =60mA AND 10Hz
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
used connected to the noise bypass pin to lower
the output noise level to 30μVrms . 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 the Iq is reduced
down to 100nA max. The internal thermal
shutdown circuitry limits the juntion 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.
