PIN I/O DESCRIPTION
NAME DRV DBV
TPS709 TPS709 TPS709A TPS709B
EN 4 3 5 5 I Enable pin. Drive this pin high to enable the device. Drive this pin low to put the device into low current shutdown. This pin can be left floating to enable the device. The maximum voltage must remain below 6.5 V.
GND 3 2 2 1 — Ground
IN 6 1 3 2 I Unregulated input to the device
NC 2, 5 4 4 4 — No internal connection
OUT 1 5 1 3 O Regulated output voltage. Connect a small 2.2-µF or greater ceramic capacitor from this pin to ground to assure stability.
Thermal pad — — — — The thermal pad is electrically connected to the GND node. Connect this pad to the GND plane for improved thermal performance.
