ZTL431AQ

Description

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 and ZTL432BQ have the same electrical specifications as the ZTL431AQ and ZTL431BQ but have 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.
