PIN DESCRIPTIONS
PIN
NO. NAME DESCRIPTION
1 OUT Regulator output. A capacitor ≥ 10 µF must be tied from this pin to ground to assure stability.
2 FB This pin is the input to the control-loop error amplifier. It is used to set the output voltage of the device.
3, 4, 6, 7 GND Ground
This pin turns the regulator on or off. If V
