DescriptionThe TL431/ TL432 are three terminal adjustable shunt regulators offering excellent temperature stability and output current handling capability up to 100mA. The output voltage may be set to any chosen voltage between 2.5 and 20 volts by selection of two external divider resistors.
The TL431/ TL432 devices can be used as a replacement for zener diodes in many applications requiring an improvement in zener performance.
The ZTL432 has the same electrical specifications as the ZTL431 but has a different pin out in SOT23 (F-suffix) and SOT23F (FF-suffix). Both variants are available in 2 grades with initial tolerances of 1% and 0.5% for the A and B grades respectively.
These are functionally equivalent to the TL431/ TL432 except for maximum operation voltage, and have an ambient temperature range of -40 to 125 as standard.
