GND 3, Pad 4 Ground. The pad must be tied to GND. Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into EN 4 5 shutdown mode. EN can be connected to IN if not used. Fixed voltage versions only; connecting an external capacitor to this pin bypasses noise NR 2 3 generated by the internal bandgap. This allows output noise to be reduced to very low levels. Adjustable version only; this is the input to the control loop error amplifier, and is used to set the FB 2 3 output voltage of the device. Output of the regulator. A small capacitor (total typical capacitance ≥ 2.0μF ceramic) is needed OUT 1 1 from this pin to ground to assure stability. N/C 5 2, 6, 7 Not internally connected. This pin must either be left open, or tied to GND. 4 Submit Documentation Feedback Copyright © 2008–2009, Texas Instruments Incorporated |
