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 V_OUT.
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 V_OUT pulled to 0v and V_IN worst case = 6.0V.
8. This specification is specified by design.
9. There is a 1 MΩ resistor between V_EN and ground on the device.
