Design ATL431, ATL432
SLVSCV5D – MARCH 2015 – REVISED OCTOBER 2016 ATL431, ATL432 2.5-V Low Iq Adjustable Precision Shunt Regulator
1 Features 3 Description 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 О©.
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. 1 Adjustable Regulated Output of 2.5 V to 36 V
