Pinout and package

Figure 2. 10-Lead LFCSP Pin Co… — Package: **10-lead, 3 mm × 3 mm LFCSP**

Pin	Name	Function	Source
3		VOUT_SENSE: Output Sense. VOUT_SENSE is internally connected to VOUT with a 10 Ω resistor. Connect VOUT_SENSE as close to the load as possible.
4		BYP: Low Noise Bypass Capacitor. Connect a 1 μF capacitor from the BYP pin to ground to reduce noise. Do not connect a load to this pin.
5		EN: Enable. Drive EN high to turn on the regulator; drive EN low to turn off the regulator. For automatic startup, connect EN to VIN.
6		REF_SENSE: Reference Sense. Connect REF_SENSE to the REF pin. Do not connect REF_SENSE to VOUT or GND.
7		REF: Low Noise Reference Voltage Output. Bypass REF to ground with a 1 μF or greater capacitor. Short REF_SENSE to REF for fixed output voltages. Do not connect a load to this pin.
8		VREG: Regulated Input Supply Voltage to Low Dropout (LDO) Amplifier. Bypass VREG to ground with a 1 μF or greater capacitor.
1, 2		VOUT: Regulated Output Voltage. Bypass VOUT to ground with a 10 μF or greater capacitor.
9, 10		VIN: Regulator Input Supply Voltage. Bypass VIN to ground with a 10 μF or greater capacitor.
EP		EP: Exposed Pad. The exposed pad is located on the bottom of the package. The exposed pad enhances thermal performance, and it is electrically connected to ground inside the package. Connect the exposed pad to the ground plane on the board to ensure proper operation.
