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.

Some questions about the generation and principle of 0-10V dimming of LED constant current power supply!
0-10V can be generated by the constant current power supply. The default pull-up resistor is 10V when powered on, so the LED brightness is 100%. The voltage can be pulled down by an external adjustabl...
