† Notice: Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only and functional operation
of the device at these or any other conditions above those
indicated in the operation sections of the specifications is not
implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.

1: VR is the nominal regulator output voltage. For example: VR = 1.8V, 2.5V, 3.3V, 4.0V, 5.0V.
The input voltage VIN = VR + 1.0V, IOUT = 40 mA.
2: TCVOUT = (VOUT-HIGH – VOUT-LOW) *106 / (VR * ΔTemperature), VOUT-HIGH = Highest voltage measured
over the temperature range. VOUT-LOW = Lowest voltage measured over the temperature range.
3: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.
