over the 10Hz to 100kHz bandwidth. If not used, this pin

must be left unconnected.

SHDNP (Pin 12): Positive Shutdown. The SHDNP pin puts

the positive side into a low power shutdown state. The

positive output will be off when the SHDNP pin is pulled

below 0.8V(typical). The SHDNP pin can be driven by 5V

logic or open-collector logic with a pull-up resistor. The

pull-up resistor is required to supply the pull-up current of

the open-collector device, normally several microamperes,

and the SHDNP pin current, typically 1μA into the pin. If

unused, the SHDNP pin must be connected to INP. The

positive output will be shut down if the SHDNP pin is open

circuit. The SHDNP pin can be tied directly to the SHDNN

pin and both pins driven directly by positive logic for a

single point control of both outputs.

PIN FUNCTIONS

NC (Pin 13): No Connect. The No Connect pin has no

connection to internal circuitry and may be tied to INP,

GND, INN, SHDNP, SHDNN, OUTP, OUTN, ﬂoated, or tied

to any other point.

INP(Pin 14): Positive Input. Power is supplied to the

positive side of the LT3032 through the INP pin. A bypass

capacitor is required on this pin if it 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 1μF

to 10μF is sufﬁcient.
