3.3 Pin Description
3.3.1 Ground
This is the common ground connection for the V
connections. It is also the 0VDC reference for the control inputs.
3.3.2 V
The positive input voltage power node to the module, which is
referenced to common GND.
3.3.3 Inhibit
The Inhibit pin is an open-collector/drain negative logic input that is
referenced to GND. Applying a low level ground signal to this input
disables the module’s output and turns off the output voltage. When
the Inhibit control is active, the input current drawn by the regulator
is significantly reduced. If the Inhibit pin is left open-circuit, the
module will produce an output whenever a valid input source is
applied.
3.3.4 V
A 0.1W, 1% tolerance (or better) resistor must be connected directly
between this pin and pin 7 (GND) pin to set the output voltage to the
desired value. The set point range for the output voltage is from 0.8V
to 3.6V. The resistor required for a given output voltage may be
calculated from the following formula. If left open circuit, the module
output will default to its lowest output voltage value.
3.3.5 V
The sense input allows the regulation circuit to compensate for
voltage drop between the module and the load. For optimal voltage
accuracy V
disconnected.
3.3.6 V
The regulated positive power output with respect to the GND node.
3.3.7 Track
This is an analog control input that allows the output voltage to
follow another voltage during power-up and power-down sequences.
The pin is active from 0V up to the nominal set-point voltage. Within
this range the module’s output will follow the voltage at the Track pin
on a volt-for-volt basis. When the control voltage is raised above this
range, the module regulates at its nominal output voltage. If unused,
this input maybe left unconnected. For further information consult
section 10.
3.3.8 Margin Down
When this input is asserted to GND, the output voltage is decreased
by 5% from the nominal. The input requires an open-collector (open-
drain) interface. It is not TTL compatible. A lower percent change can
be accomodated with a series resistor.
3.3.9 Margin Up
When this input is asserted to GND, the output voltage is increased
by 5%. The input requires an open-collector (open-drain) interface. It
is not TTL compatible. The percent change can be reduced with a
series resistor.
