Pin Functions

PIN I/O DESCRIPTION
NAME DQN DBV DBZ YKA
IN 4 1 3 A1 Input Input pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground as listed in the Recommended Operating Conditions table. Place the input capacitor as close to input of the device as possible.
EN 3 3 B1 Input Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables the device. If enable functionality is not required, this pin must be connected to IN. VEN must not exceed VIN.
GND 2 2 1 B2 Ground pin. This pin must be connected to ground on the board.
OUT 1 5 2 A2 Output Regulated output pin. A capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger ceramic capacitor from OUT to ground. Follow the recommended capacitor value as listed in the Recommended Operating Conditions table. Place the output capacitor as close to output of the device as possible.
NC 4 No connect pin. This pin is not internally connected. Connect to ground or leave floating.
Thermal pad Pad Connect the thermal pad to a large-area ground plane. This pad is not an electrical connection to the device ground.
