† 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.
