NAME (KTT) (DRB) DESCRIPTION
Connecting an external capacitor to this pin bypasses noise generated by the internal
NR 5 5
bandgap. This improves power-supply rejection and reduces output noise.
FB 5 5 This terminal is the feedback input voltage for the adjustable device.
EN 1 8 Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator
into shutdown mode. EN can be connected to IN if not used.
GND 3, Tab 6, PowerPAD Regulator ground
IN 2 1, 2 Unregulated input to the device.
OUT 4 3, 4 Output of the regulator.
