Notes: 1. All voltages are with respect to the potential at the GND pin.

2. Min and Max limits are specified by design, test, or statistical analysis. Typical numbers are not ensured,

but do represent the most likely norm.

3. The device maintains a stable, regulated output voltage without a load current.

4. Quiescent current is defined here as the difference in current between the input voltage source and the

load at VOUT.

5. Ground current is defined here as the total current flowing to ground as a result of all input voltages applied

to the device.

6. Dropout voltage is the voltage difference between the input and the output at which the output voltage

drops to 100 mV below its nominal value. This parameter only applies to output voltages above 2.5V.

7. Short Circuit Current is measured with VOUT pulled to 0v and VIN worst case = 6.0V.

8. This specification is specified by design.

9. There is a 1 MΩ resistor between VEN and ground on the device.
