pin FuncTions
BYPN (Pin 11): Negative Bypass. The BYPN pin is used
to bypass the reference of the negative side regulator to
achieve low noise performance. A small capacitor from
OUTN to this pin will bypass the reference to lower the
output voltage noise. A maximum value of 0.01µF is used
for reducing output voltage noise to a typical 30µV
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 0.6V(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 microam-
peres, and the SHDNP pin current, typically 1µA into the
pin. If unused, the SHDNP pin must be connected to INP .
RMS
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.
NC (Pin 13/Pins 2, 8 for Fixed Voltage Devices): No Con-
nect. 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.
