Frequently Asked Questions
What is the output voltage range and maximum current of the TL431ACLP?
The TL431ACLP is adjustable from 2.495V to 36V using external resistors, with a maximum output sink current of 100mA (0.1A), and a tightly controlled reference voltage window of 2.495V minimum to 2.52V maximum for precision voltage regulation applications.
What package does the TL431ACLP use and how is it classified?
The TL431ACLP uses a 3-pin TO-92 through-hole package (JESD-30 code O-XBCY-T3) and is classified as a two-terminal adjustable shunt voltage reference. It is Pb-free with JESD-609 code e3, meeting RoHS compliance for global regulatory requirements.
What are the most common applications for the TL431ACLP?
The TL431ACLP is widely used in switching power supply feedback loops (including flyback converters with optocouplers), linear regulator control circuits, battery chargers, overvoltage protection circuits, and any application requiring a programmable precision voltage reference from 2.495V to 36V with a 100mA sink capability.
How does the TL431ACLP achieve its adjustable output voltage?
The output voltage is set by a simple external resistor divider connected from the output to the reference pin (REF). The device regulates the output to maintain the REF pin at the internal 2.495V reference, so choosing appropriate resistor values allows the output to be programmed anywhere from 2.495V up to 36V within the supply voltage constraints.
