(2) It is recommended that the thermal pad be grounded. Table 1. PIN DESCRIPTIONS PIN NAME DRV DDC DESCRIPTION Regulated output voltage pin. A small (1mF) ceramic capacitor is needed from this pin to OUT 1 5 ground to assure stability. See the Input and Output Capacitor Requirements in the Application Information section for more details. N/C 2 — Not connected. Driving the enable pin (EN) over 1.2V turns ON the regulator. Driving this pin below 0.4V EN 4 3 puts the regulator into shutdown mode, reducing operating current to 18nA typical. GND 3, 5 2, 4 ALL ground pins must be tied to ground for proper operation. Input pin. A small capacitor is needed from this pin to ground to assure stability. Typical input IN 6 1 capacitor = 1.0mF. Both input and output capacitor grounds should be tied back to the IC ground with no significant impedance between them. Thermal pad Thermal pad — It is recommended that the thermal pad on the SON-6 package be connected to ground. 4 Submit Documentation Feedback Copyright © 2008–2010, Texas Instruments Incorporated |
