OM186ST

1. Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.

2. Line and load regulation are guaranteed up to the maximum power dissipation. Power dissipation is determined by

the input/output differential voltage and output current. Guaranteed maximum power dissipation will not be available

over the full input/output voltage range.

3. I FULL LOAD curve is defined as the minimum value of current limit as a function of input to output voltage.

Note that power dissipation is only achievable over a limited range of input to output voltage.

4. Dropout voltage is specified over the full output current range of the device.
