Note 2. Unless otherwise specified, these specifications apply for temperatures within the operating

temperature range, for input and output voltages within the range given, and for a divider

impedance seen by the feedback terminal of 2kΩ. Load and line regulation specifications

are for a constant junction temperature. Temperature drift effects must be taken into account

separately when the unit is operating under conditions of high dissipation.

Note 3. The output currents given, as well as the load regulation, can be increased by the addition

of external transistors. The improvement factor will be roughly equal to the composite cur-

rent gain of the added transistors.

Note 4. With no external pass transistor.
