Adjustable Regulator Feedback Input: Connect to the resistor voltage divider that is
placed from OUT to GND in order to set the output voltage.
Input Bias Voltage: Voltage for powering all internal circuitry of the regulator with the
exception of the output power device.
Ground: TAB is also connected internally to the IC’s ground on D-Pak.
Input Voltage: Supplies the current to the output power device
Regulator Output: The output voltage is set by the resistor divider connected from OUT
to GND (with the divided connection tied to ADJ). A minimum value capacitor must be
used to maintain stability. See Applications Information.
