KA431AZTF Datasheet

Voltage & Current References


The KA431 / KA431A / KA431L / KA431AZTF are three-terminal adjustable regulators with a guaranteed thermal stability over the operating temperature range. 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 dynamic output impedance of 0.2 Ω. Active output circuitry provides a sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications. KA431AZTF 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
