Overview
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 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.
