SENSE (Pin 1):
This pin is the positive side of the reference
voltage for the device. With this pin it is possible to Kelvin
sense the output voltage at the load.
ADJ (Pin 2/5):
This pin is the negative side of the
reference voltage for the device. Transient response can
be improved by adding a small bypass capacitor from the
ADJ pin to ground. For fixed voltage devices the ADJ pin
is also brought out to allow the user to add a bypass
capacitor
.
GND (Pin 2, 7-Lead Only):
For fixed voltage devices this
is the bottom of the resistor divider that sets the output
voltage.
(5-Lead/7-Lead)
V
POWER
(Pin 5/6):
This is the collector to the power device
of the LT1580. The output load current is supplied through
this pin. For the device to regulate, the voltage at this pin
must be between 0.1V and 0.8V greater than the output
voltage (see Dropout specifications).
V
CONTROL
(Pin 4/3):
This pin is the supply pin for the
control circuitry of the device. The current flow into this
pin will be about 1% of the output current. For the device
to regulate, the voltage at this pin must be between 1.0V
and 1.3V greater than the output voltage (see Dropout
specifications).
V
OUT
(Pin 3/4):
This is the power output of the device.
