PIN FUNCTIONS (SOT-23 Package/DD Package) IN (Pin 1/Pin 8):
Input. Power is supplied to the device logic with a pull-up resistor. The pull-up resistor is only through the IN pin. A bypass capacitor is required on this required to supply the pull-up current of the open-collec- pin if the device is more than six inches away from the main tor gate, normally several microamperes. If unused, the input fi lter capacitor. In general, the output impedance of SHDN pin must be tied to IN or to a logic high. a battery rises with frequency, so it is advisable to include
ADJ (Pin 4/Pin 2):
Adjust. This is the input to the error a bypass capacitor in battery-powered circuits. A bypass amplifi er. This pin is internally clamped to ±7V. It has a capacitor in the range of 0.1μF to 10μF is suffi cient. The bias current of 4nA which fl ows into the pin (see curve LT3014 is designed to withstand reverse voltages on the IN of ADJ Pin Bias Current vs Temperature in the Typical pin with respect to ground and the OUT pin. In the case of Performance Characteristics). The ADJ pin voltage is a reversed input, which can happen if a battery is plugged 1.22V referenced to ground, and the output voltage range in backwards, the LT3014 will act as if there is a diode in is 1.22V to 60V. series with its input. There will be no reverse current fl ow into the LT3014 and no reverse voltage will appear at the
OUT (Pin 5/Pin 1):
Output. The output supplies power to load. The device will protect both itself and the load. the load. A minimum output capacitor of 0.47μF is required to prevent oscillations. Larger output capacitors will be
GND (Pin 2/Pins 4, 9):
Ground. required for applications with large transient loads to limit
SHDN (Pin 3/Pin 5):
Shutdown. The SHDN pin is used peak voltage transients. See the Applications Information to put the LT3014 into a low power shutdown state. The section for more information on output capacitance and output will be off when the SHDN pin is pulled low. The reverse output characteristics. SHDN pin can be driven either by 5V logic or open-collector 3014fd 7
