The ATL431 and ATL432 are three-terminal
adjustable shunt regulators, with specified thermal
stability over applicable automotive, commercial, and
industrial temperature ranges. The output voltage can
be set to any value between Vref (approximately
2.5 V) and 36 V, with two external resistors. These
devices have a typical output impedance of 0.05 Ω.
Active output circuitry provides a very sharp turn-on
characteristic, making these devices excellent
replacements for Zener diodes in many applications,
such as onboard regulation, adjustable power
supplies, and switching power supplies.
The ATL43x has > 20x improvement cathode current
range over it's TL43x predecessor. It also is stable
with a wider range of load capacitance types and
values.
ATL431 and ATL432 are the exact same parts but
with different pinouts and order numbers. The
ATL43x is offered in two grades, with initial
tolerances (at 25°C) of 0.5%, 1%, for the B and A
grade, respectively. In addition, low output drift vs
temperature ensures consistent voltage regulation
over the entire temperature range. ATL431AIDBZR ATL431AQDBZR ATL431BIDBZR ATL431BQDBZR ATL432AIDBZR
