Terminal Functions TERMINAL SOT223 (DCQ) DDPAK SON 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. 4 Submit Documentation Feedback Copyright © 2002–2008, Texas Instruments Incorporated |
