B Grade? A Grade? No internal connection NC? No internal connection? Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. No internal connection TL The output voltage can be set to any value between Vref approximately 2.
These devices have a typical output impedance of 0. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.
In addition, low output drift vs temperature ensures good stability over the entire temperature range. Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www. REF ? All component values are nominal. Cathode voltage, VKA see Note 1. A to 10 mA Operating virtual junction temperature, TJ.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The deviation parameters Vref dev and Iref dev are defined as the differences between the maximum and minimum values obtained over the recommended temperature range. Maximum Vref 10 6 Minimum Vref? TA is the recommended operating free-air temperature range of the device. Figure 1. R1 Figure 3.
