Notes:

1. Load regulation is specified for an output load change of 10% to 100%.

2. Measured at an internal IC junction.

3. Quiescent current is specified at 0% load for Vin = min to max.

4. This regulator is not designed to be used in parallel with another unit to increase output power.

5. The remote on/off control current is typically 2 µA. Shutdown

input current is 30 µA max. The On/Off shutdown threshold

voltage is 1.1V to 1.4V.

6. The input should not exceed the range given in the model

selection chart. Exceeding this limit could damage the unit.
