SNVSCR4 July 2024 TLA431
ADVANCE INFORMATION
When the cathode/output voltage or current of TLA431 is not being fed back to the reference/input pin in any form, this device is operating in open loop. With proper cathode current (Ika) applied to this device, TLA431 has the characteristics shown in Figure 9-4. With such high gain in this configuration, TLA431 is typically used as a comparator. With the reference integrated makes TLA431 the prefered choice when users are trying to monitor a certain level of a single signal.
