LT3023
PIN FUNCTIONS
GND (Pin 3): Ground.
ADJ1/ADJ2 (Pins 4/2): Adjust Pin. These are the inputs to
the error ampli?ers. These pins are internally clamped to
± 7V. They have a bias current of 30nA which ?ows into the
pin (see curve of ADJ1/ADJ2 Pin Bias Current vs Tempera-
ture in the Typical Performance Characteristics section).
The ADJ1 and ADJ2 pin voltage is 1.22V referenced to
ground and the output voltage range is 1.22V to 20V.
BYP1/BYP2 (Pins 5/1): Bypass. The BYP1/BYP2 pins are
used to bypass the reference of the LT3023 regulator to
achieve low noise performance from the regulator. The
BYP1/BYP2 pins are clamped internally to ±0.6V (one V BE )
from ground. A small capacitor from the corresponding
output to this pin will bypass the reference to lower the
output voltage noise. A maximum value of 0.01μF can
be used for reducing output voltage noise to a typical
20μV RMS over a 10Hz to 100kHz bandwidth. If not used,
this pin must be left unconnected.
OUT1/OUT2 (Pins 6/10): Output. The outputs supply power
to the loads. A minimum output capacitor of 1μF 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.
SHDN1 / SHDN2 (Pins 7/9): Shutdown. The SHDN1 / SHDN2
pins are used to put the corresponding channel of the
LT3023 regulator into a low power shutdown state. The
output will be off when the pin is pulled low. The SHDN1 /
SHDN2 pins can be driven either by 5V logic or open-col-
lector logic with pull-up resistors. The pull-up resistors
are required to supply the pull-up current of the open-
collector gates, normally several microamperes, and the
SHDN1 / SHDN2 pin current, typically 1μA. If unused, the
pin must be connected to V IN . The device will not function
if the SHDN1 / SHDN2 pins are not connected.
IN (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 1μF to 10μF is suf?cient. The
LT3023 regulator is designed to withstand reverse volt-
ages on the IN pin with respect to ground and the OUT
pin. In the case of a reverse input, which can happen if
a battery is plugged in backwards, the device will act as
if there is a diode in series with its input. There will be
no reverse current ?ow into the regulator and no reverse
voltage will appear at the load. The device will protect both
itself and the load.
Exposed Pad (Pin 11): Ground. This pin must be soldered
to the PCB and electrically connected to ground.
