ZTL431xQ/ZTL432xQ
AUTOMOTIVE COMPLIANT ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
The ZTL431xQ and ZTL432xQ 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 ZTL432xQ has the same electrical specifications as the
ZTL431xQ but has a different pin out in SOT23 (F-suffix) and
SOT23F (FF-suffix).
