A small (1- μF) ceramic capacitor is needed from this pin to OUT 1 5 O ground to assure stability. See the Input and Output Capacitor Requirements in the Application and Implementation section for more details. NC 2 — — No internal connection. Enable pin. Drive this pin over 1.2 V to turn on the regulator. Drive this pin below 0.4 V to EN 4 3 I put the regulator into shutdown mode, reducing operating current to 18 nA typical. GND 3, 5 2, 4 — Ground pin. Tie all ground pins to ground for proper operation. Input pin. For stable operation, place a small, 0.1-µF capacitor from this pin to ground; IN 6 1 I typical input capacitor = 1.0 µF. Tie back both input and output capacitor grounds to the IC ground, with no significant impedance between them. Thermal Thermal — — Connect the thermal pad to ground. pad pad Copyright © 2008–2015, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: TPS782 |
