For ensured specifications and the test conditions, see the Electrical Characteristics. If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. The maximum power dissipation is a function of TJ(max) , θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–T A)/θJA. All numbers apply for packages soldered directly into a PC board. For testing purposes, ESD was applied using human body model, 1.5 kΩ in series with 100 pF.

As shown in Figure 3, this voltage is applied across resistor R1 to generate a constant current I1. This constant current then flows through R2. The resulting voltage drop across R2 adds to the reference voltage to sets the desired output voltage. The current IADJ from the adjustment terminal introduces an output error. But since it is small (120μA max), it becomes negligible when R1 is in the 100Ω range. For fixed voltage devices, R1 and R2 are integrated inside the devices.
