control inputs.

The Inhibit pin is an open-collector/drain, active-low 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 feature is not used, the control pin

should be left open-circuit. The module then produces an output voltage whenever a valid input source is applied.

A 1% resistor must be connected directly between this pin and GND (pin 1 or 2) to set the output voltage of the

module higher than its lowest value. The temperature stability of the resistor should be 100 ppm/

°C (or better).

The set-point range is 0.8 V to 3.6 V. The resistor value can be calculated using a formula. If this input is left

open-circuit, the output voltage defaults to its lowest value. For further information, consult the related application

note.

The specification table gives the standard resistor values for a number of common output voltages.

The sense input allows the regulation circuit to compensate for voltage drop between the module and the load. For

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 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

NOTE: Due to the undervoltage lockout feature, the output of the module cannot follow its own input voltage

during power up. Consult the related Application Information for further guidance.
