ONSEMI KA431SMFTF Voltage Regulator

The KA431S / KA431SA / KA431SL are three-terminal adjustable regulators with guaranteed thermal stability across full temperature ranges, output voltage adjustable between 2.5 V and 36 V using two resistors. Featuring low dynamic impedance of 0.2 Ω, these devices support sink currents from 1.0 to 100 mA and have a temperature coefficient of 50 ppm/°C. They exhibit fast turn-on, low noise, and are suitable replacements for zener diodes in various control and regulation applications, with full lead-free and halogen-free compliance.
