Pin Functions PIN I/O DESCRIPTION NAME SON SOT Regulated output voltage pin. A small (1- μF) ceramic capacitor is needed from this pin to OUT 1 5 O ground to assure stability. See Input and Output Capacitor Requirements for more details. N/C 2 — — Not connected. Feedback pin (FB) for adjustable versions; VSET for fixed voltage versions. Drive the select VSET/FB 3 4 I pin (VSET) below 0.4 V to select preset output voltage high. Drive the VSET pin over 1.2 V to select preset output voltage low. 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 5 2 — Ground pin. Tie all ground pins to ground for proper operation. Input pin. A small capacitor is needed from this pin to ground to assure stability. A typical IN 6 1 I input capacitor is 1.0 μF. Tie back both input and output capacitor ground to the IC ground, with no significant impedance between them. Thermal — — — (SON package only) Connect the thermal pad to ground. pad Copyright © 2007–2015, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: TPS780 |
