IN (Pin 1/Pin 8):
Input. Power is supplied to the device
through the IN pin. A bypass capacitor is required on this
pin if the device is more than six inches away from the main
input filter capacitor. In general, the output impedance of
a battery rises with frequency, so it is advisable to include
a bypass capacitor in battery-powered circuits. A bypass
capacitor in the range of 0.1
μ
F to 10
μ
F is sufficient. The
LT3014 is designed to withstand reverse voltages on the
IN pin with respect to ground and the OUT pin. In the case
of a reversed input, which can happen if a battery is
plugged in backwards, the LT3014 will act as if there is a
diode in series with its input. There will be no reverse
current flow into the LT3014 and no reverse voltage will
appear at the load. The device will protect both itself and
the load.
GND (Pin 2/Pins 4, 9):
Ground.
SHDN (Pin 3/Pin 5):
Shutdown. The SHDN pin is used to
put the LT3014 into a low power shutdown state. The
output will be off when the SHDN pin is pulled low. The
SHDN pin can be driven either by 5V logic or open-
collector logic with a pull-up resistor. The pull-up resistor
is only required to supply the pull-up current of the open-
collector gate, normally several microamperes. If unused,
the SHDN pin must be tied to IN or to a logic high.
