s INTERNAL CURRENT AND THERMAL LIMIT
s VOUT TOLERANCE ± 2% (AT 25°C)
DESCRIPTION
The LK112S 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.
SOT23-5L
The LK112S 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.
