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

Note 2: Line and load regulation are guaranteed up to the maximum power dissipation (OM185/20W, OM186/10W).

Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum

power dissipation will not be available over the full input/output voltage range.

Note 3: IFULL 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.

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

The • denotes the specifications which apply over the full operating temperature range.
