PIN DESCRIPTION
NAME TYPE
GND — Ground pin.
IN Input Input supply pin. See the Recommended Operating Conditions table and the Input and Output Capacitor Selection section for more information.
OUT Output Output of the regulator. 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; see the Recommended Operating Conditions table and the Input and Output Capacitor Selection section. Place the output capacitor as close to output of the device as possible.
EN Input Enable pin. Driving the enable pin high enables the device. Driving this pin low disables the device. High and low thresholds are listed in the Electrical Characteristics table. This pin has a weak internal pullup and can be left floating to enable the device or the pin can be connected to the input pin. Refer to Enable (EN) section.
ADJ Input When using the adjustable device, this pin sets the output voltage with the help of a feedback divider. In the adjustable configuration, this pin must be connected through a resistor divider to the output for the device to function.
NC — Not internally connected. Leave this pin open or connected to any potential. Tie this pin to ground for improved thermal performance.
Thermal pad Thermal pad. Connect the pad to GND for the best possible thermal performance. See the Layout section for more information.
