Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.
Please
email any questions regarding the system integration to

KA431 / KA431A / KA431L — Programmable Shunt Regulator
July 2013
KA431 / KA431A / KA431L
Programmable Shunt Regulator
Features
Programmable Output Voltage to 36 V
Low Dynamic Output Impedance: 0.2
Ω
(Typical)
Sink Current Capability: 1.0 to 100 mA
Equivalent Full-Range Temperature Coefficient
of 50 ppm/°C (Typical)
• Temperature Compensated for Operation
Over Full Rated Operating Temperature Range
• Low Output Noise Voltage
• Fast Turn-on Response
Description
The KA431 / KA431A / KA431L are three-terminal
adjustable regulators with a guaranteed thermal stability
over the operating temperature range. The output volt-
age can be set to any value between V
REF
(approxi-
mately 2.5 V) and 36 V with two external resistors.
These devices have a typical dynamic output impedance
of 0.2
Ω.
Active output circuitry provides a sharp turn-on
characteristic, making these devices excellent replace-
ments for Zener diodes in many applications.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at T
