DESCRIPTION

NAME

DBV

YZQ

Enable pin. 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.

—

Feedback pin. This terminal is the feedback input pin for the adjustable device. Fixed voltage

versions in the DBV package do not have this pin.

GND

—

Regulator ground.

Input to the device.

NR/NC

—

Noise Reduction pin (legacy chip only). Connecting an external capacitor to this pin filters

noise generated by the internal bandgap. This configuration improves power-supply rejection

and reduces output noise for the legacy chip and YZQ package only.

No Connect pin (new chip only). This pin is not internally connected. Connect to GND for

improved thermal performance or leave floating. For lower noise performance on a fixed

device, consider looking at the TPS7A20.

OUT

Output of the regulator.
