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 that offer excellent temperature
stability and output current handling capability up to 100mA. The
output voltage can be set to any chosen voltage between 2.5V and
20V by the 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).

The ZTL431AQ, ZTL431BQ, ZTL432AQ, and ZTL432BQ are
available in two grades with initial tolerances of 1% and 0.5% for the
A and B grades respectively.
These devices are functionally equivalent to the TL431/TL432 except
for maximum operation voltage, and they have an ambient
temperature range of -40°C to +125°C as standard.
