KA431S / KA431SA / KA431SL
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 KA431S / KA431SA / KA431SL are three-terminal
adjustable regulator series with a guaranteed thermal
stability over the operating temperature range. The out-
put voltage can be set to any value between VREF
(approximately 2.5 V) and 36 V with two external resis-
tors. 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 replacement for Zener diodes in many applica-
tions.
