Note 1: Power dissipation is 150 mW in free air. Power dissipation is 500 mW when mounted as recommended. Derate at 4.0 mW/°C for operation
above 25°C.
Note 2: This value depends on the output voltage. This is a reference value for a 3 V output device.
Note 3: The input current decreases to the pA level by connecting the control terminal to GND.
Note 4: The pull-down resistor is not built-in.
Note 5: The minimum operating voltage for VIN can be 1.8 V. Also, the minimum voltage required for VIN is VIN = VDROP + VOUT. As a result, operating
at VOUT £ 2.0 V at the mimimum input operating voltage is not preferred.
General Note: Parameters with only typical values are just reference. (Not guaranteed)
General Note: The operation of -30 °C to 80 °C is guaranteed by design (verified by sample inspection).
General Note: Exceeding the “Absolute Maximum Rating “may damage the device.
General Note: Connecting a capacitor to the noise by pass pin will decrease the output noise voltage.
