PIN NO.

PIN NO.

5

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 Applications Information for more details.

EN can be connected to IN if not used.

NR

4

4

Fixed voltage versions only—connecting an external capacitor to this pin bypasses noise

generated by the internal bandgap. This allows output noise to be reduced to very low levels.

FB

4

4

Adjustable voltage version only—this is the input to the control loop error amplifier, and is used to

set the output voltage of the device.

OUT

5

2

Output of the Regulator. There are no output capacitor requirements for stability.
