ZTL431AQ, ZTL431BQ
ZTL432AQ, ZTL432BQ
AUTOMOTIVE COMPLIANT ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
The ZTL431AQ, ZTL431BQ, ZTL432AQ and ZTL432BQ 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 ZTL432AQ, ZTL432BQ has the same electrical specifications as
the ZTL431AQ, ZTL431BQ but has a different pin out in SOT23 (F-
suffix) and SOT23F (FF-suffix).

The ZTL431AQ, ZTL431BQ, ZTL432AQ and ZTL432BQ 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°C to +125°C as standard.
