DESCRIPTION
NAME
NO.
This is the common ground connection for the VI and VO power connections. It is also the 0-VDC reference for
GND
1
the Inhibit , VO Adjust, and Track control inputs.
This is an analog control input that enables the output voltage to follow an external voltage. This pin becomes
active typically 20 ms after the input voltage has been applied, and allows direct control of the output voltage
from 0 V up to the nominal set-point voltage. Within this range, the output voltage follows 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 set-point voltage. The feature allows the output voltage to rise simultaneously with other modules powered
from the same input bus. If unused, this input should be connected to VI.
NOTE: Due to the undervoltage lockout feature, the output of the module cannot follow its own input voltage
during power up. For more information, consult the related application section.
VI
3
I
The positive input voltage power node to the module, which is referenced to common GND.
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. When the Inhibit control is active, the input current

I
drawn by the regulator is significantly reduced. If the Inhibit pin is left open-circuit, the module produces an
output voltage whenever a valid input source is applied. Do not place an external pull-up on this pin.
A 1% resistor must be connected between this pin and GND (pin 1) to set the output voltage of the module
higher than 0.9 V. If left open-circuit, the output voltage defaults to this value. The temperature stability of the
VO Adjust

I
resistor should be 100 ppm/
°C (or better). The set-point range is from 0.9 V to 5.5 V. The electrical
specification table gives the standard resistor value for a number of common output voltages. See the
application information for further guidance.
VO
6
O
The regulated positive power output with respect to the GND node.
