LT3014
PIN FUNCTIONS
(SOT-23 Package/DD Package)
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 ?lter 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 0.1μF to 10μF is suf?cient. 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 ?ow
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-collec-
tor gate, normally several microamperes. If unused, the
SHDN pin must be tied to IN or to a logic high.
ADJ (Pin 4/Pin 2): Adjust. This is the input to the error
ampli?er. This pin is internally clamped to ±7V. It has a
bias current of 4nA which ?ows into the pin (see curve
of ADJ Pin Bias Current vs Temperature in the Typical
Performance Characteristics). The ADJ pin voltage is
1.22V referenced to ground, and the output voltage range
is 1.22V to 60V.
OUT (Pin 5/Pin 1): Output. The output supplies power to
the load. A minimum output capacitor of 0.47μF is required
to prevent oscillations. Larger output capacitors will be
required for applications with large transient loads to limit
peak voltage transients. See the Applications Information
section for more information on output capacitance and
reverse output characteristics.
