FUNCTION
DESCRIPTION
1
Sense
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.
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 adjust pin to ground.
This is the power output of the device, and is electrically connected to
the TAB.
This pin is the supply pin for the control circuitry for the device. The
current flow into this pin will be approximately 1% of the output. 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).
This is the collector input to the power device of the L1581. The output
load current is supplied through this pin. For the device to regulate, the
voltage on this pin must be between 0.1V and 0.7V greater than the
output, depending upon load current (see dropout specifications).
