PIN I/O DESCRIPTION
NAME NO.
X2SON SOT-23
EN 3 3 I Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables the device. Do not float this pin. If not used, connect EN to IN.
GND 2 2 Ground pin. This pin must be connected to ground on the board.
IN 4 1 I 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 for best thermal performance or leave floating.
OUT 1 5 O Regulated output pin. A 1-µF or greater effective capacitance is required from OUT to ground for stability. see the Recommended Operating Conditions table. 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.
Thermal pad The thermal pad is electrically connected to the GND pin. Connect the thermal pad to a large-area GND plane for improved thermal performance.
