Pin Functions: YKA PIN NAME YKA(1) I/O DESCRIPTION
Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables EN A2 Input the device. If enable functionality is not required, this pin must be connected to IN. VEN must not exceed VIN. GND A1 — Ground pin. This pin must be connected to ground and the thermal pad.
ADV
Input pin. A 0.1-µF or greater effective capacitance is required from IN to ground to minimize IN B2 Input input impedance. For best transient response, use a 1-µF or larger ceramic capacitor from IN to ground. Place the input capacitor as close to input of the device as possible. Regulated output pin. A 0.5-µF or greater effective capacitance is required from OUT to ground
ANCEINFORMA
OUT B1 Output 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. (1) Preview package.
