PIN DESCRIPTIONS
Pin 1:
VEN: Enable input. Pulling this pin under 0.4V turns the regulator off, reducing the quiescent current
to a fraction of its operating value. The device will be enabled if this pin is left open. Connect
to VIN if not being used.
Pin 2: VIN: Power input pin. Supply the power to the IC.
Pin 3: VO: The pin is the power output of the regulator. Its voltage is 1.6 times of VSET.
Pin 4: VSET: This pin sets the output voltage. Its voltage must be larger than 1V to guarantee VO as 1.6
times of VSET.
Pin 5: GND: Reference ground. Use all four pins on the SOP-8 device.
Pin 6: GND: Reference ground. Use all four pins on the SOP-8 device.
Pin 7: GND: Reference ground. Use all four pins on the SOP-8 device.
Pin 8: GND: Reference ground. Use all four pins on the SOP-8 device.
