Pin Functions: DQN, DBV PIN I/O(1) DESCRIPTION NAME DQN DBV EN 3 3 Input Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low or floating this pin disables the device. This pin features an internal pulldown resistor, which is disconnected when EN is driven high externally and the device has started up. GND 2 2 — Ground pin. This pin must be connected to ground on the board. IN 4 1 Input Input pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground; see the Recommended Operating Conditions table. Place the input capacitor as close to the input of the device as possible. NC — 4 — No connect pin. This pin is not internally connected. Connect to ground or leave floating. OUT 1 5 Output Regulated output pin. A 0.5-µF or greater effective capacitance is required from OUT to ground for stability. For best transient response, use a 1-µF or larger ceramic capacitor from OUT to ground. Place the output capacitor as close to output of the device as possible; see the Recommended Operating Conditions table. Thermal pad –– — Connect the thermal pad to a large-area ground plane. The thermal pad is internally connect to ground. |
