PIN (DCQ) (DRB) (DRV)
NAME PIN NO. PIN NO. PIN NO. DESCRIPTION
IN 1 8 6 Unregulated input supply
GND 3, 6 4, Pad 3, Pad Ground
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts
the regulator into shutdown mode. Refer to the Shutdown section under
EN 5 5 4
Applications Information for more details. EN must not be left floating and can
be connected to IN if not used.
Fixed voltage versions only—connecting an external capacitor to this pin
NR 4 3 2 bypasses noise generated by the internal bandgap, reducing output noise to
very low levels.
Adjustable voltage version only—this is the input to the control loop error
FB 4 3 2
amplifier, and is used to set the output voltage of the device.
OUT 2 1 1 Regulator output. A 1.0μF or larger capacitor of any type is required for stability.
NC — 2, 6, 7 5 Not connected
