LT3010/LT3010-5
3010f
OUT (Pin 1):
Output. The output supplies power to the
load. A minimum output capacitor of 1
μ
F is required to
prevent oscillations. Larger output capacitors will be re-
quired 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.
SENSE (Pin 2):
Sense. For the LT3010-5, the SENSE pin
is the input to the error amplifier. Optimum regulation will
be obtained at the point where the SENSE pin is connected
to the OUT pin of the regulator. In critical applications,
small voltage drops are caused by the resistance (R
P
) of
PC traces between the regulator and the load. These may
be eliminated by connecting the SENSE pin to the output
at the load as shown in Figure 1 (Kelvin Sense Connec-
tion). Note that the voltage drop across the external PC
traces will add to the dropout voltage of the regulator. The
SENSE pin bias current is 10
μ
A at the nominal rated output
voltage.
ADJ (Pin 2):
Adjust. For the adjustable LT3010, this is the
input to the error amplifier. This pin is internally clamped
to
±
7V. It has a bias current of 50nA which flows into the
pin (see curve of ADJ Pin Bias Current vs Temperature in
the Typical Performance Characteristics). The ADJ pin
voltage is 1.275V referenced to ground, and the output
voltage range is 1.275V to 60V.
GND (Pin 4, Tab):
Ground. The exposed backside of the
package is an electrical connection for GND. As such, to
ensure optimum device operation, the exposed pad must
be connected directly to pin 4 on the PC board.
SHDN (Pin 5):
Shutdown. The SHDN pin is used to put the
LT3010 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-collector gate,
normally several microamperes. If unused, the SHDN pin
can be left open circuit. The device will be active, output
on, if the SHDN pin is 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
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 1
μ
F to 10
μ
F is sufficient. The
LT3010 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 LT3010 will act as if there is a
diode in series with its input. There will be no reverse
current flow into the LT3010 and no reverse voltage will
appear at the load. The device will protect both itself and
the load.
